The international break might bring respite from the packed club calendar, but with Qatar 2022 now just 20 months away, top players have little chance for rest.

Still, the start of the European World Cup qualifiers brings an opportunity for the new names on the international scene to impress, particularly with more established stars unlikely to be involved in every minute of matches over these two weeks.

Several of the continent's top teams have offered first-time call-ups to those enjoying fine form and, while some were anticipated, others have left even the players themselves surprised.

We have picked through a selection of the new faces to look out for, with a sprinkling of Opta data to highlight why they deserve a chance to impress for their country.

Belgium: Orel Mangala and Albert Sambi Lokonga

Stuttgart's Orel Mangala has been linked with Arsenal and RB Leipzig due to his performances for Stuttgart this season. Only three midfielders have regained possession more often in the Bundesliga than the 23-year-old (166).

Also hoping to make his senior Belgium debut at the heart of midfield is Albert Sambi Lokonga, who assumed the captain's armband at Anderlecht less than a month after turning 21.

Lokonga, who could get a chance in place of the injured Axel Witsel, has regained possession 35 more times than any team-mate this season (157) and is also fourth for chances created (22).

Croatia: Kristijan Lovric

With Ante Rebic and Bruno Petkovic injured, the coming matches could offer a real chance to impress for Kristijan Lovric.

The HNK Gorica star is second in the top scorer standings in Croatia's top flight, with 15 goals in 24 appearances. With four assists also to his name, Lovric is behind only Tottenham's Europa League slayer Mislav Orsic and Ramon Mierez (both on 20) for direct goal involvements this season.

It's a seriously impressive return for the 25-year-old, particularly as he plays predominantly wide on the left of the Gorica attack.

England: Ollie Watkins

West Brom goalkeeper Sam Johnstone may get the chance to win a first senior England cap, but a man almost certain to be given a chance in attack is Ollie Watkins.

The Aston Villa forward became the 10th Premier League player to score a hat-trick against Liverpool, and the first in a decade, in October's extraordinary 7-2 win over the reigning champions.

He has 10 in the top flight this term, while only captain Jack Grealish (17) has had more direct goal involvements than Watkins (15) in all competitions for Villa this season. Not bad for a man who was playing in England's sixth tier just six years ago.

Germany: Florian Wirtz and Jamal Musiala

Rising Bayern Munich star Jamal Musiala was expected to be named in Joachim Low's squad after he pledged his international future to Germany rather than England.

The 18-year-old, who only signed his first professional contract this month, is Bayern's youngest ever Champions League goalscorer and has already played 18 times in the Bundesliga this season.

Bayer Leverkusen's Florian Wirtz has also earned the right to shine on the senior stage. He is one of just two players under the age of 20 to be directly involved in at least eight goals across the top-five European leagues this season.

Italy: Rafael Toloi and Matteo Ricci

Brazilian-born Rafael Toloi has made it to the age of 30 without a senior international appearance, but his performances for Gian Piero Gasperini's outstanding Atalanta side made him hard to overlook.

Toloi averages seven possession regains per match for Atalanta this season and is comfortable when using the ball, completing 493 passes in the opposition half, the most of any Atalanta defender barring Berat Djimsiti.

Spezia midfielder Matteo Ricci, meanwhile, boasts 19 chances created in Serie A this season as well as 151 times winning back the ball, by far the highest tally for his team.

Netherlands: Jeremiah St Juste

Jeremiah St Juste has impressed at the back for Mainz this season, despite their involvement in a tense battle to avoid the drop.

There are only five Bundesliga defenders to win more tackles and duels combined than the 24-year-old this season (he has managed 165).

Previously a full-back with Feyenoord, St Juste brings a vital commodity to modern central defending: speed. Last season, he clocked a sprint of 22.1 miles per hour, bettered only at the time by Bayern winger Kingsley Coman.

Poland: Kacper Kozlowski

A relative unknown outside Poland, even Kacper Kozlowski himself was shocked to be called up to Paulo Sousa's squad this month.

Clearly, though, he has caught the eye for some all-action displays in the top flight for Pogon Szczecin. The 17-year-old averages 8.3 duels won and 17 passes ending in the final third per 90 minutes, each the most of any teenage midfielder in the competition.

Kozlowski, who is also renowned for a fierce long-range shot, has been linked with some of the world's biggest clubs since making his senior debut at just 15, with Manchester United said to be among them.

Portugal: Joao Palhinha and Nuno Mendes

Linked with Manchester City (among others), Sporting CP full-back Nuno Mendes has been described as the standout young talent in Portugal's top flight.

Only Wilson Manafa (49) has completed more dribbles among defenders this season than Mendes (29), who has played in all but four of the unbeaten leaders' league matches.

The 18-year-old is joined in the Portugal squad by team-mate Joao Palhinha, a robust midfielder who has won 208 duels in the Primeira Liga in 2020-21 – no player in his position has won more.

Spain: Bryan Gil and Pedri

Pedri has been a revelation for Barcelona in his first season at Camp Nou, establishing himself as a key part of Ronald Koeman's midfield despite only turning 18 last November.

He has played 42 times already in 2020-21, the most of anyone at the club, and became the youngest player to record 100 touches in a single LaLiga game for at least 15 years against Osasuna this month.

Bryan Gil, meanwhile, has been thriving on loan at Eibar from Sevilla and in January became the second player born this century to score twice in the same LaLiga match, following in the footsteps of Ansu Fati.

Cristiano Ronaldo has not been affected by Juventus' recent struggles, insists Portugal head coach Fernando Santos. 

The Bianconeri were eliminated from the Champions League in the last-16 stage by Porto a fortnight ago, going out on away goals after the tie finished 4-4 on aggregate after extra time at the Allianz Stadium.

Former Juve boss Fabio Capello singled out Ronaldo for criticism, while ex-president Giovanni Cobolli Gigli suggested the club should never have spent €100million to sign the forward in 2018.

Andrea Pirlo's side bounced back from that defeat with a 3-1 win over Cagliari in Serie A, but their hopes of securing a 10th consecutive Scudetto were left in tatters at the weekend following a shock 1-0 home loss to Benevento. 

Ronaldo, who has been linked with moves to former clubs Real Madrid and Manchester United, has since joined up with the Portugal squad for their World Cup qualifiers against Azerbaijan, Serbia and Luxembourg.

And Santos says has no concerns over the 36-year-old's morale. 

"We've always been close to each other, very good friends, we don't really have a coach-player relationship," Santos told a media conference.

"Ronaldo certainly represents great quality; he always shows great happiness and joy when he's with the team.

"He's an important player, probably the best in the world. I don't think he has any problem in terms of mentality at the moment."

Portugal are red-hot favourites to progress from Group A, which also contains the Republic of Ireland, but Santos insists they will not be complacent as they bid to book their place in Qatar in search of a first-ever World Cup triumph. 

“We mustn't underestimate anyone," he added. “We know Azerbaijan can be quite dangerous on the counter-attack.

"We know Ronaldo always wants to conquer new trophies, but all the players want to win the World Cup. We can fight to become world champions."

Cristiano Ronaldo's club future may be unclear but Portugal coach Fernando Santos insists the 36-year-old is dreaming about playing at and winning next year's World Cup.

Ronaldo has been linked with a move away from Juventus this close season, including speculation linking him with MLS, along with a possible return to Real Madrid.

Amid that, Santos moved to clarify that the five-time Ballon d'Or winner was committed to playing for Portugal at the World Cup as they chase their maiden Jules Rimet Trophy.

"[Cristiano] has a big dream, that one I know," Santos said.

"He has this big dream of participating in what we are setting out to do, that is the goal of playing in a World Cup and winning it.

"That is the main goal, the rest has to stay away from the national team."

Ronaldo has played at four World Cups, with Portugal's best result during his time being in 2006 when they came fourth in Germany, while they were knocked out in the last 16 in both 2010 and 2018.

Portugal finished third at the 1966 World Cup before failing to qualify again for the tournament for another 20 years.

They won Euro 2016 with Ronaldo scoring three goals in the campaign, although he went off injured early in the final.

Portugal will return to competitive action later this month with World Cup qualifiers against Azerbaijan, Serbia and Luxembourg.

Portugal coach Fernando Santos has defended his decision to call up Rui Patricio for this month's World Cup qualifiers.

The Wolves goalkeeper suffered a sickening blow to the head after colliding with team-mate Conor Coady during Monday's 1-0 Premier League loss to Liverpool.

He was taken off on a stretcher after a lengthy delay to the match, but Wolves boss Nuno Espirito Santo confirmed after the match that Patricio had avoided serious injury.

The 33-year-old was named as part of the Portugal squad on Tuesday ahead of the upcoming games against Azerbaijan, Serbia and Luxembourg.

Santos told reporters: "He's been called up because, from the moment it happened, we tried to find out everything that was going on.

"We talked to him and the medical department. He's stable. He has a protocol to follow but they said there was no hindrance."

Alongside established stars such as Cristiano Ronaldo, Joao Felix, Bernardo Silva, Bruno Fernandes and Ruben Dias, Santos granted recalls to striker Andre Silva and Arsenal full-back Cedric Soares.

There were also debut call-ups to Sporting CP full-back Nuno Mendes and his midfield team-mate Joao Palhinha.

Santos said he had given Palhinha "a positive assessment, otherwise he wouldn't be here", adding: "There were other options.

"He's had very positive form. It's important for him to come at this moment because there isn't a very long international break and it's important for me to evaluate him more closely."

Portugal squad:

Anthony Lopes (Lyon), Rui Patricio (Wolves), Rui Silva (Granada); Joao Cancelo (Manchester City), Cedric Soares (Arsenal), Domingos Duarte (Granada), Pepe (Porto), Jose Fonte (Lille), Ruben Dias (Manchester City), Raphael Guerreiro (Borussia Dortmund), Nuno Mendes (Sporting CP); Danilo Pereira (Paris Saint-Germain), Joao Palhinha (Sporting CP), Ruben Neves, Joao Moutinho (both Wolves), Bruno Fernandes (Manchester United), Renato Sanches (Lille), Sergio Oliveira (Porto); Bernardo Silva (Manchester City), Pedro Neto (Wolves), Diogo Jota (Liverpool), Cristiano Ronaldo (Juventus), Rafa Silva (Benfica), Joao Felix (Atletico Madrid), Andre Silva (Eintracht Frankfurt).

Ole Gunnar Solskjaer is weighing up whether to block Manchester United star Bruno Fernandes from travelling with Portugal during the international break due to COVID-19 quarantine.

Portugal are scheduled to play three World Cup qualifiers this month – at home to Azerbaijan (March 24), away to Serbia (March 27) and on the road against Luxembourg (March 30).

Linking up with Portugal would mean Fernandes would be subject to a 10-day quarantine in a government-approved hotel upon his return to the United Kingdom amid the coronavirus pandemic.

It would also leave Solskjaer without the services of Fernandes against Brighton and Hove Albion (April 3) and Tottenham (April 10).

Asked about the situation following Wednesday's goalless draw away to Crystal Palace, United manager Solskjaer told reporters: "We have not sat down and made a proper call on that one but it doesn't make sense if you lose your player for 10 days' isolation.

"We are the ones paying the players, from what I understand, that [being allowed to ban players travelling] is the rule. 

"FIFA have given the rule that they don't have to be released, so it is going to be a hard call to make to let them play in red-list countries.

"I want Bruno ready for Brighton and hopefully we will be through in Europe and against Tottenham after that break, of course I do."

United were held to their third successive scoreless draw across all competitions after firing another blank against Palace midweek.

Solskjaer's faltering United produced another toothless display at Selhurst Park, where the Red Devils slipped 14 points adrift of runaway leaders Manchester City ahead of Sunday's derby.

United registered their sixth goalless Premier League draw of the season – the club's joint-most ever in a campaign, along with 2004-05 and 2016-17.

The Premier League giants have also drawn three consecutive matches 0-0 in all competitions for the first time since October 2015 under Louis van Gaal.

"Of course we're not happy when you don't create chances enough to win a game," Solskjaer said. "Of course, it's been a week with no goals, and sometimes three games sounds a lot without scoring.

"It was not considered either but a week in a season like this sometimes is... yeah, you just don't hit the form that you normally had, that you have had for many, many months, so it's a bit of a worry. Of course it is.

"But, I know that the boys are given everything. And that's the thing with we play every three days, and I know they given everything they've got so attitude and approach I'm very happy with the quality. We need to get back to what we know we can do."

Cristiano Ronaldo has not yet broken Josef Bican's all-time goalscoring record in official matches, according to the Czech FA.

Superstar Juventus forward Ronaldo scored his 760th competitive goal in the 2-0 Supercoppa Italiana victory over Napoli on Wednesday.

It was reported by some that Ronaldo had surpassed Bican's benchmark, while others stated he had equalled it and alternative sources claimed the legendary Rapid Vienna and Slavia Prague striker actually netted 805 - FIFA itself uses this number as an estimate.

Confused yet? Well, this wonderfully convoluted tale is complicated further by the fact Brazil legends Pele and Romario each claim to have scored 1,000 career goals – though both are disputed by official sources.

And to really compound the matter, the bright minds of the History and Statistics Committee of the Czech FA have been delving deep into the archives to reach the conclusion that Bican – who played internationally for Austria and Czechoslovakia – actually scored 821 goals, meaning Ronaldo would still need another 62.

Probably best we leave the explanation for this one to Jaroslav Kolar, the head of the committee…

"Who is the best goalscorer in football history? Josef Bican or Cristiano Ronaldo?" Was the question posed by Kolar on the official account for the Czech Republic national team.

"A simple question but a complicated answer." (We quite agree...)

Anyway, he added: "Mainly because from the whole amount of Bican's goals, you have to just pick up the official ones, which is complicated. 

"Our History and Statistics Committee of [the] Czech FA started to deal with this problem. We based our research on statistics from prestigious international statistical websites that state 805 goals with notice that goals scored by Bican in the Czech second division for Hradec Kralove are missing. 

"We managed to find them - by the way, it's 53 goals in 26 games and we also double checked every detail about Bican's league, cup and international matches. 

"After that, we came out with the official number of Josef Bican's scored goals. On behalf of the History and Statistics Committee of [the] Czech FA, we can proclaim Josef Bican scored 821 goals in official matches. 

"It means that Cristiano Ronaldo is not the best goalscorer in international history yet, and he has to work more to break this record."

So, that settles that argument then!

Or does it? Quite honestly... we have no idea.
