World number five Stefanos Tsitsipas cruised into the Mexican Open final with a routine victory over Italian teenage sensation Lorenzo Musetti in Acapulco on Friday.

Tsitsipas triumphed 6-1 6-3 in 79 minutes to get past 19-year-old Musetti, who had beaten third seed Diego Schwartzman and former world number three Grigor Dimitrov on his run to the semis.

The Greek top seed will play second seed Alexander Zverev in Saturday's final after the German got past countryman Dominik Koepfer 6-4 7-6 (7-5) in their semi-final, which was literally rocked by an earthquake.

The broadcast cameras shook mid-point but play continued as a 5.7 magnitude earthquake was registered to the north of Marquelia, which is to the east of Acapulco.

Tsitsipas holds a 5-1 record against Zverev, who is ranked seventh in the world and made last year's US Open final.

"Sascha is someone I've played against in the past and it's never easy. We're both really hungry and we're both very competitive," Tsitsipas said.

The Greek made light work of Musetti, winning five straight games in the opening set after starting at 1-1.

Unforced errors cost Musetti, who had his moments, but Tsitsipas was on song with 17 of 23 winners off his forehand.

Musetti will move into the top 100 of the rankings for the first time on Monday after his breakthrough week.

"We'll definitely see a lot from Lorenzo in the future, he has a wonderful one-handed backhand and creates lots of opportunities. He showed his level this week," Tsitsipas said.

For the first time since 2005, neither Lionel Messi nor Cristiano Ronaldo will be involved in the Champions League quarter-finals.  

While Barcelona's exit to last season's runners-up Paris Saint-Germain was perhaps not too much of a surprise, few saw Juventus coming out on the wrong end of an upset against Porto in the last 16.  

So, could we be witnessing a changing of the guard in the competition? Is it a case of out with the old, in with the new? 

While Messi and Ronaldo have dominated in Europe through the years, a collection of some of the most promising talents in the world game have the chance to take centre stage now.

Erling Haaland (Borussia Dortmund)

Even by his own prolific standards, Haaland has been in sensational scoring form in the tournament so far.

His 10 goals in six games includes scoring a brace in each leg of the last-16 tie with Sevilla, helping Borussia Dortmund progress to the quarters.  

The Norwegian striker managed the same number in a Champions League campaign last season that saw him represent both BVB and Salzburg. Forget just breaking the record as the fastest to 20 goals, he has shattered it. Harry Kane was previously the quickest to reach that number, doing so in 24 games – Haaland managed it in just 14. 

His big chance conversion rate this season sits at a clinical 81.9 per cent, while he has also demonstrated his all-round impact by creating eight chances for his BVB colleagues.  

Next in his sights is Manchester City, a team with family ties as his father, Alf-Inge, played for the English club in the early 2000s. Haaland has been linked with them too, along with plenty of other clubs, and Pep Guardiola has been suitably impressed by a player who does not turn 21 until July.  

"The numbers speak for themselves, of course he is one of the best strikers in the world right now at his age," said Guardiola, who will be well aware that Haaland has the potential to ruin City's hopes of European glory. 

Kylian Mbappe (Paris Saint-Germain)

Mbappe has six goals to his name in European outings in 2020-21, the same tally team-mate Neymar has managed for a PSG squad aiming to go one better than last year.

The France international hit a hat-trick in a 4-1 thrashing of Barcelona at Camp Nou, joining Faustino Asprilla and Andriy Shevchenko as the only players to record a Champions League treble against the Spanish heavyweights.  

He was also on target when scoring a penalty in the drawn second leg, in the process becoming the youngest player to reach 25 goals in the competition, aged 22 years and 80 days. Messi was on the same pitch at the time his record was broken. 

Mbappe has also demonstrated how he can provide for others, too. No forward from any of the teams still in contention can top his three assists, while only Karim Benzema (15) has bettered his total of 14 chances created. 

PSG will be hoping the forward can continue his fine form when they take on Bayern Munich in a repeat of last year's final.

Phil Foden (Manchester City)

After three starts in the Champions League last season, Foden has risen from the periphery to become a prominent figure for Guardiola.  

Only goalkeeper Ederson has played more minutes in the campaign so far for City than the versatile 20-year-old, who has contributed a goal and two assists to help ensure smooth progress to the last eight.  

Foden has created the most chances for City during his appearances, his tally of 12 putting him just ahead of Kevin De Bruyne (11), while he has also been successful with 64.7 per cent of his attempted dribbles.  

The playmaker is set to feature in the Champions League knockout stage for a fourth season before turning 21 – a feat only previously achieved by Cesc Fabregas (2004-05 to 2007-08) and Theo Walcott (2006-07 to 2009-10).  

In the Premier League, Foden's 20 goal involvements (11 goals, nine assists) is comfortably the most by anyone aged 21 or under, showing just why he is no longer one to watch for the future but a player for the present, both for club and country.

Alphonso Davies (Bayern Munich)

It is not often a full-back catches the eye to the level that Davies managed during Bayern's triumphant Champions League run in 2019-20.  

The most eye-catching moment of all surely came in his side's 8-2 rout of Barcelona in a quarter-final result that sent shock waves across European football, as he initially beat two opposing players before breezing beyond poor Nelson Semedo to set up a goal for Joshua Kimmich, one of his three assists in the competition.  

Having arrived at the Bundesliga club as a left winger, the conversion to defence was made as quickly as he sprints up and down his flank (he clocked a top speed of 36.51 kilometres per hour in a Bundesliga game against Werder Bremen last year, the quickest speed recorded since such data began to be collected).  

His participation in the group stage this season was limited by an ankle injury, with the 4-1 first-leg victory over Lazio in the last 16 just his second start.  

However, the Canada international had no problems upon his return, having 101 touches (second only to team-mate David Alaba) while topping the list for Bayern in terms of tackles (four) and number of times possession was gained from the opposition (seven).

The Brooklyn Nets' six-game winning streak came to a grinding halt with a 121-113 loss to the lowly Orlando Magic, despite the return of Kyrie Irving after groin soreness.

The Magic were coming into the match on a nine-game losing streak, but jumped out of the blocks with Aaron Gordon scoring 21 points in the first half.

Orlando led by as many as 12 points in the second quarter before the Nets closed to trail by only two at the main break, led by Irving, who finished with a game-high 43 points, six rebounds and four assists.

James Harden's output was slightly down, finishing with 19 points, four rebounds and nine assists as Orlando raced away again in the third.

Gordon finished with a season-high 38 points, Evan Fournier scored 31, while center Nikola Vucevic had 22 points, 14 rebounds and eight assists as the Magic pulled off an upset.

The Utah Jazz returned to the winners' list with a thrilling 115-112 triumph over the Toronto Raptors, who have now lost seven in a row.

The Jazz had lost four of six coming into the match, but found some form, led by Donovan Mitchell with 31 points and five rebounds, the star pinching the lead late after the Raptors were up by five with 90 seconds to go.

Pascal Siakam put up a three-point attempt on the buzzer which cruelly rimmed out.

Blazers do it again, Wiggins' season high

CJ McCollum and Damian Lillard produced another special performance as the Portland Trail Blazers came from behind again to win their third straight game, 125-119 over the Dallas Mavericks.

McCollum finished with 32 points, including seven three-pointers, while Lillard had 31 points along with six assists as Portland scored 32 points to 21 in the last to win. The victory was also Portland's Terry Stotts' 500th as head coach.

Andrew Wiggins produced a season-high 40 points, including six three-pointers, eight rebounds and four steals as the Golden State Warriors beat the Memphis Grizzlies 116-103.

Nikola Jokic sparkled with 34 points, 15 rebounds and nine assists as the Denver Nuggets edged the Chicago Bulls in overtime 131-127. Jamal Murray also scored 34 for Denver.

Guard Malcolm Brogdon scored 27 points as the Indiana Pacers piled on the points in a 137-110 win over the Miami Heat.

Mason Plumlee had 16 rebounds while Frank Jackson scored 23 points as the struggling Detroit Pistons won back-to-back games, 113-100 over the Houston Rockets, who have lost 19 in a row.

Melo makes history

Trail Blazers forward Carmelo Anthony, 36, scored 18 points in Portland's win but he also brought up the milestone of 27,000 NBA points, becoming only the 11th player to reach the figure.

Eighth seed Ann Li toppled the top remaining seed Zheng Saisai in the quarter-finals of the Monterrey Open on Friday, throwing the field wide open.

Li triumphed 7-5 6-1 over third seed Zheng, who held the highest rank of all remaining players after Sloane Stephens and Nadia Podoroska's first-round exits.

World number 52 Zheng struggled to win on her first serve, with Li converted five of seven break points.

American Li, who is ranked 72nd in the world, will next face Swiss qualifier Viktorija Golubic, who beat Russia's Anna Kalinskaya 6-2 6-4.

On the other side of the draw, Canadian Leylah Fernandez defeated Slovakia's Viktoria Kuzmova 7-5 6-3 and will face seventh seed Sara Sorribes Tormo in the other semi-final.

Sorribes Tormo, who is now the highest ranked remaining player, defeated Anna Karolina Schmiedlova 6-3 7-5.

An earthquake hit Acapulco during Alexander Zverev's clash against Dominik Koepfer at the Mexican Open on Friday.

The broadcast camera shook mid-point during the all-German semi-final encounter.

A 5.7 magnitude earthquake was registered to the north of Marquelia, which is to the east of Acapulco.

Zverev went on to secure a 6-4 7-6 (7-5) victory over Koepfer to reach the final.

Thomas Tuchel has no concerns over the application or attitude of Tammy Abraham and Billy Gilmour, but he understands their frustration at a lack of game time.

Abraham has not featured for Chelsea since February 20, while Gilmour has made just one appearance, in an FA Cup tie against Barnsley last month, under Tuchel.

With Euro 2020 coming up at the end of the season, both players missed out on their respective national squads for the upcoming March internationals.

Tuchel knows this could be of concern but insisted that he was at fault in Abraham's case, rather than the striker, who has scored six league goals this season.

"He's had a bit of a tough time," Tuchel said of Abraham in a news conference previewing Sunday's FA Cup clash with Sheffield United.

"He suffers a little bit also from me not finding the real formation up front. Like, 'Okay, let's play always like this, this is your position, these are the guys you compete against, try to compete against A, B and C and therefore you can go'.

"It's a bit more complex because I need to get to know the team better. We have Timo [Werner] who can play as a number nine, we have Olivier [Giroud] and Kai [Havertz], so he suffers a little bit from all these circumstances.

"It's not his fault, it is also maybe more my fault than his fault. We have some talks now to encourage him never to give in, to accept the situation and to not overthink it and to just come back to the momentum in training and to stay positive.

"The team is winning now without him, he could feel a bit excluded, but it is not like this with him so hopefully he can be back now in the squad, be totally free. There are some hard choices, there's still a long way to go and he’s part of it."

Across all competitions, Abraham averages a goal every 127 minutes, while he boasts an admirable big chance conversion rate of 62.5 per cent (10/16).

All 12 of Abraham's goals this season have come from inside the box, and his shooting accuracy stands at 51.22 per cent – excluding blocked efforts.

Asked if England international Abraham had voiced any concern over his participation in the Euros, Tuchel replied: "We have not talked about this. I feel more concerned about his role in our team.

"He clearly knows a role in our team improves the chances for him to have a role in the English national team, for sure.

"We did not talk about it, but it would not surprise me if it's in his head. This is totally normal that the players have their own interests to have a role in their team but also for their country.

"I hope that he's not too harsh on himself and does not overthink it. What is important is the situation in the club and he has every chance to find his way back."

In Gilmour's case, Tuchel stressed the Scottish youngster's limited opportunity has been merely down to the quality of Chelsea's midfield options.

"He has three big problems – N'Golo Kante, Kovacic and Jorginho," Tuchel said.

"They are never injured and perform on a level in central midfield, it is not easy to compete with them. This is the only thing. I have no trust issue with him, I have no problem with his attitude."

Pep Guardiola has no regrets over Jadon Sancho's decision to leave Manchester City, insisting he is thrilled the winger has gone on to become a star for Borussia Dortmund. 

Frustrated by the lack of a clear pathway from City's academy through to the first team, Sancho left Manchester in 2017 to continue his career in Germany, just a year into Guardiola's tenure. 

It was hailed as a brave decision by the 17-year-old at the time, though he broke into Dortmund's side during his first season with the club, scoring once in 12 league appearances. However, Sancho blossomed from a promising talent to a verified superstar during the 2018-19 campaign.  

He will get the chance to shine against his former side in the Champions League next month, with Dortmund drawn against City in the quarter-finals. 

Yet despite Sancho's transformation into one of Europe's finest attacking talents, Guardiola has no hard feelings over the player's choice to leave City. 

"I said many times, not a regret, he decides," Guardiola told a news conference. 

"He's doing really well, congratulations, an exceptional player. A national team player with huge quality, doing really well in Dortmund. 

"We wanted him to stay but he decided to leave – when they decide to leave all we can do is [let them] leave. I wish him all the best except when he plays against us. If he's happy, I'm happy." 

Since the start of the 2018-19 season, Sancho has provided 48 assists across all competitions – 22 more than Marco Reus, who ranks second for Dortmund across the same period of time – with BVB winning 72 of the 118 games he has featured in. 

Only Erling Haaland (47) can better Sancho's goal tally of 45, while he leads the way for chances created with 251 – an impressive 101 more than second-placed Raphael Guerreiro. 

Of those opportunities, 56 have been categorised as 'big chances', which are judged by Opta as those where it is expected a player should score. 

Sancho also compares favourably when up against some of City's squad. Only the exceptional Kevin De Bruyne has created more chances (343) in the same timeframe, while the Belgian has crafted 87 big chances. 

De Bruyne's assist tally stands at 48, level with Sancho, who ranks behind just City trio Raheem Sterling (69), Sergio Aguero (58) and Gabriel Jesus (56) in terms of goals scored.

Guardiola, though, remains philosophical about Sancho's choice.  

"Nobody knows – maybe he stays and we don't play good or better. Every person decides the life they lead, other people have to respect it," he continued. "We want him, he decides to go, all the best." 

Seven of Sancho's goals have come from fast breaks, outlining his importance to Dortmund when they are able to counter-attack opponents. 

Haaland is second in Dortmund's squad in that regard with five fast-break goals, with Guardiola well aware of the task City face in trying to keep BVB's vibrant attack at bay. 

"We will face him, try to control him. We know the quality he has, everyone knows," said Guardiola of Haaland, son of former City player Alf-Inge. 

"The individual quality in Dortmund is from all departments, a strong team. In the Champions League, they always have done well."

World number one Novak Djokovic has joined Rafael Nadal and Roger Federer in deciding not to play at the Miami Open, which begins next week.

The Masters 1000 tournament has not been its usual big draw for the leading men this year, and Djokovic becomes the latest high-profile withdrawal.

The 33-year-old Serbian announced he would enjoy some family time rather than travel to the United States, citing the need for balance in his life as coronavirus restrictions affect globe-trotting sports stars.

Miami's total prize fund is said to have been cut from $16.7million in 2019, the last time it was held, to $6.68m this year.

That drastic reduction, reported by the Tennis Majors website, may or may not have been a partial factor in the withdrawals that have dented the top-tier quality in the men's side of the tournament.

The women's event looks like being a full-strength field, while new world number two Daniil Medvedev is set to be the men's top seed, providing he makes the trip.

Djokovic wrote on Twitter: "Dear fans, I'm very sorry to announce that this year I won't travel to Miami to compete.

"I decided to use this precious time at home to stay with my family. With all restrictions, I need to find balance in my time on tour and at home. I look forward to coming back next year!"

Nadal has been bothered by a back problem and cited it earlier this week as the reason for his withdrawal, as he looks to recover full fitness in time for the clay-court season and a crack at winning a 14th French Open title.

The Spaniard's great rival Federer, a fellow 20-time grand slam winner, has only just returned from a year away from the tour after knee surgery, and beat Dan Evans in his first match back at the Qatar Open before losing to Nikoloz Basilashvili.

Federer then elected not to play in Dubai and will not be in Miami, where he is the men's reigning champion, having taken the 2019 title. The 2020 tournament was cancelled because of the COVID-19 crisis.

Andrey Rublev's ATP 500 winning streak came to an end at the hands of Aslan Karatsev on a history-making day at the Dubai Tennis Championships.

Rublev had won 23 consecutive matches at this level, second only to Roger Federer (28), but Karatsev finally ended the Russian's remarkable run to progress to his first ATP singles final.

Karatsev, who incredibly went from qualifying to the semi-finals of the Australian Open this year, defeated his compatriot 6-2 4-6 6-4.

He became the first Wild Card to reach the final since Thomas Muster in 1997, doing so by hitting 41 winners and forcing 16 break points – of which he won four – during two hours and 12 minutes on court.

"It was a really tight match [against a] tough opponent," Karatsev said in his on-court interview.

"It was an unbelievable performance [from Andrey]. He didn't lose a match at an ATP 500 in [one year]. Everything was decided in one or two points, I feel happy."

The championship match will be between two first-time Dubai finalists after Lloyd Harris stunned Denis Shapovalov in the other semi-final.

World number 81 Harris, who overcame top seed Dominic Thiem, 14th seed Filip Krajinovic and former US Open finalist Kei Nishikori to reach the last four, came from a set and 4-2 down to defeat world number 12 Shapovalov.

He prevailed 6-7 (5-7) 6-4 7-6 (8-6) to reach a maiden ATP 500 final and become the first qualifier to reach the showpiece in Dubai.

"I don't have many words right now. I am super happy with that win," Harris said on court afterwards.

"Being a set and 2-4 down is mentally and physically a little bit troublesome for me, but I found my best tennis from there. I am just extremely happy with the result right now."

Italy boss Roberto Mancini handed first call-ups to Atalanta captain Rafael Toloi and Spezia midfielder Matteo Ricci as he selected a 38-man squad for the three upcoming World Cup qualifiers. 

Brazilian-born Toloi has been residing in Italy since leaving Sao Paulo to join Atalanta in 2015 and has received the citizenship that makes him eligible to represent the Azzurri. 

The 30-year-old has been summoned at the first opportunity by head coach Mancini, who has observed the centre-back as a prominent member of the Atalanta team that has caught the eye in Serie A and the Champions League. 

Ricci, 26, joined Spezia from Roma in July 2018 and helped the team win promotion to Serie A last season. 

He has yet to score in the top flight for Spezia this term but has had two assists and created 16 chances, while winning possession 139 times, a team-high mark. 

Italy face Northern Ireland in Parma in their Group C qualifying opener next Thursday, then tackle Bulgaria in Sofia on March 28 before playing Lithuania three days later in Vilnius. 

The Inter trio of Alessandro Bastoni, Nicolo Barella and Stefano Sensi will only be involved if they have the all-clear from health authorities, given they are currently subject to COVID-19 restrictions after positive tests at the club. 

Inter's Stefan de Vrij and Matias Vecino tested positive for coronavirus, and the Nerazzurri said on Thursday all players would be prevented from joining up with their international teams, although that may change if they return negative test results on Monday. 

The Italian Football Federation (FIGC) said Ricci must also be similarly cleared to join up. 

Italy are unbeaten in 22 games and have qualified for both Euro 2020, which takes place in June and July, and the Nations League Finals in October. 

Italy squad: Alessio Cragno (Cagliari), Gianluigi Donnarumma (Milan), Alex Meret (Napoli), Salvatore Sirigu (Torino); Francesco Acerbi (Lazio), Alessandro Bastoni (Inter), Cristiano Biraghi (Fiorentina), Leonardo Bonucci (Juventus), Giorgio Chiellini (Juventus), Giovanni Di Lorenzo (Napoli), Emerson Palmieri (Chelsea), Gian Marco Ferrari (Sassuolo), Alessandro Florenzi (Paris Saint-Germain), Manuel Lazzari (Lazio), Gianluca Mancini (Roma), Leonardo Spinazzola (Roma), Rafael Toloi (Atalanta); Nicolo Barella (Inter), Gaetano Castrovilli (Fiorentina), Bryan Cristante (Roma), Manuel Locatelli (Sassuolo), Rolando Mandragora (Torino), Lorenzo Pellegrini (Roma), Matteo Pessina (Atalanta), Matteo Ricci (Spezia), Stefano Sensi (Inter), Roberto Soriano (Bologna), Marco Verratti (Paris Saint-Germain); Andrea Belotti (Torino), Domenico Berardi (Sassuolo), Federico Bernardeschi (Juventus), Francesco Caputo (Sassuolo), Federico Chiesa (Juventus), Stephan El Shaarawy (Roma), Vincenzo Grifo (Friburgo), Ciro Immobile (Lazio), Lorenzo Insigne (Napoli), Moise Kean (Paris Saint-Germain).

Daria Kasatkina and wildcard Margarita Gasparyan sank the top two seeds at the St Petersburg Ladies Trophy, where the semi-finals will be all-Russian showdowns.

Ekaterina Alexandrova, the number one seed, fell 6-2 7-5 to Gasparyan, before former top-10 star Kasatkina continued her recent revival by landing a 1-6 6-1 6-2 victory against Veronika Kudermetova.

Friday marked the first time at a WTA tournament that as many as seven of the final eight players have been Russian, and the day's opening clash produced a significant upset.

It was a valid reminder of what might have been for world number 126 Gasparyan, who like Alexandrova is 26 years old but has struggled massively with injuries over the years.

Gasparyan was particularly helped by her superior form on first serve in the opening set, putting 72.7 per cent in court to 44 per cent by her opponent and winning 75 per cent of points when landing that delivery.

A topsy-turvy second set saw a total of seven breaks between the two players, but Gasparyan's 4-3 advantage in that respect helped her clinch a first WTA 500 semi-final appearance.

Up next for her is 36-year-old Vera Zvonareva, the former world number two who beat Anastasia Gasanova 6-3 6-1, saving six of seven break points en route to victory.

Romania's Jaqueline Cristian was the final non-Russian player left in the draw and she certainly tested Svetlana Kuznetsova, but ultimately the 35-year-old fourth seed prevailed 6-7 (5-7) 6-3 6-3.

Next for former US Open and French Open winner Kuznetsova will be Kasatkina, who rounded off the day by shaking off a slow start to look highly impressive against second seed Kudermetova.

The 23-year-old Kasatkina has endured a couple of lean years since entering the top 10 in October 2018 but landed a title last month at the Phillip Island Trophy.

Asked about how she came back from being trounced in the opening set by Kudermetova, Kasatkina said on Amazon Prime: "I think it's just women's tennis and this is what tennis is all about.

"It took me some time to get into this match but at the end I won it."

As for how Saturday's clash with Kuznetsova might play out, Kasatkina said: "We trained many times together but never played in an official match so it's hard to say."

Jamal Musiala should not change his approach while away with Germany, Hansi Flick insisted after the Bayern Munich teenager was handed his first senior international call-up. 

Having elected to represent Germany ahead of England, whom he played for at youth level, Musiala was selected by Joachim Low for Die Mannschaft's upcoming World Cup qualifiers with Iceland, Romania and North Macedonia. 

Musiala has made 18 Bundesliga appearances in 2020-21 – only four players who are younger than him (18 years, 21 days) have played in more matches across the top five European leagues this term. 

On target in a 4-1 win over Lazio in the Champions League last month, Musiala has demonstrated impressive composure for someone of his tender years. 

And Flick believes displaying the same level-headed attitude will be the key for Musiala in his international career. 

"He should approach it the same way he does things with us, by staying calm. He's an exceptional player," Flick told a media conference ahead of Bayern's Bundesliga clash with Stuttgart. 

Bayern have been pitted against Paris Saint-Germain in the Champions League quarter-finals having eased past Lazio 6-2 on aggregate in the last 16. 

It is a rematch of last year's final, with the reward for winning the tie a semi-final meeting with either Manchester City or Borussia Dortmund.

But the renewal of acquaintances with PSG is not in Flick's immediate focus.

"My focus is on the game against Stuttgart, first and foremost," he said about the draw. "This will be our 18th game in 11 weeks.

"The team has, in this short time, delivered many strong performances once again, including in the most recent games.

"Now comes first Stuttgart, then the important game in Leipzig. We have enough time to prepare for Paris.

"Manchester City is currently one of the most consistent teams in Europe, so it is a challenge for us and Dortmund. We play the Champions League for that. 

"But we and Dortmund have the opportunity to go one round further.

"It's important to play two games at the highest level. Of course, it's a tough opponent, as you saw in the final. But we also have tremendous quality."

Teenagers Jamal Musiala and Florian Wirtz have been called up to Germany's senior squad for the first time, but there is still no place for Thomas Muller, Mats Hummels or Jerome Boateng. 

Musiala, 18, pledged his allegiance to Germany last month having previously represented England at every level from Under-15 to Under-21. 

The versatile attacker played in the Chelsea academy from 2011 until 2019 before opting to move back to Germany, where the Stuttgart-born youngster has since made quite the impression at Bayern Munich. 

He has made 18 Bundesliga appearances this term – only four players who are younger than him (18 years, 21 days) have played in more matches across the top five European leagues this term. 

One of those is Wirtz, who has shown immense promise at Bayer Leverkusen since making his debut shortly after his 17th birthday in May last year. 

With four goals and as many assists in 21 Bundesliga games, Wirtz – a technically gifted attacking midfielder – is one of only two players under the age of 20 (along with Arnaud Kalimuendo) across the top European leagues to be involved in eight league goals. 

Similarly, across those same leagues, Adil Aouchiche (46) is the only individual yet to turn 20 with more key passes than Wirtz's tally of 37.

Joachim Low, who earlier this month confirmed he will leave his post later this year, is urging both players to relax despite the added pressures that come with international recognition. 

"We are excited to get to know Jamal Musiala and Florian Wirtz even better," he told the German Football Association (DFB). "They earned the nomination with their recent good performances. 

"But especially with such young players, our responsibility is to be careful with them and lead them step by step to the highest level. 

"Both have huge potential, and I am sure that we will have a lot of fun with them in the next few years, but at the moment it is important not to rush into anything, they should take it easy and develop carefree. I think the next few days will be a good experience for Jamal and Florian." 

Amin Younes, who has been impressing with Eintracht Frankfurt this term, has earned his first call-up since October 2017, while Marc-Andre ter Stegen, Emre Can, Lukas Klostermann and Kai Havertz all return after missing the November internationals, which included a 6-0 humiliation by Spain. 

However, there is still no recall for Bayern duo Muller and Boateng, nor Borussia Dortmund centre-back Hummels. 

All three World Cup winners were cast aside by Low in March last year as he looked to refresh the squad in the wake of the 2018 World Cup failure. 

Earlier this month, Low did not rule out potentially bringing them back into the fold given their solid form at club level, yet he has ignored them again on this occasion as Germany begin their World Cup qualification campaign with games against Iceland, Romania and North Macedonia.
