Xavi has declared it a priority for Barcelona to tie down their bright young stars to new contracts, to stave off the threat of other clubs pouncing.

Ahead of a clash with Sevilla on Tuesday that Xavi described as "a huge opportunity" for Barcelona, the head coach stressed his desire to keep hold of the players coming through the club's ranks.

They are set to form the backbone of Barcelona's first team for years to come, providing they can be retained, and already the club have made serious efforts in that regard.

Pedri recently signed a deal tying him to Barcelona until 2026, and Ansu Fati has committed until 2027.

Nico Gonzalez, described by Xavi on Monday as "a total footballer", has a deal running until 2024, and Gavi is reportedly close to signing a long-term deal that Xavi wants to see get over the line.

Ez Abde joined from Hercules at the end of the last transfer window and went into the Barcelona B squad, but he has recently been featuring in the first team and it may be the case that his contract is soon upgraded to reflect that promotion.

Gavi has been this season's revelation, with the 17-year-old midfielder impressing to such an extent he has already been capped by Spain.

It was pointed out to Xavi on Monday that Gavi is one of the lowest-paid players in the Barcelona squad. The teenager reportedly has a deal that runs until 2023, and Barcelona want to make it a longer-term arrangement.

"We must act to renew him. If necessary, we will put the money together. We cannot lose these players: Nico, Pedri, Ansu, Abde, [Ronald] Araujo. I understand that the club is already working, and it is essential for the team," Xavi said.

Barcelona sit seventh in LaLiga as they prepare to tackle Julen Lopetegui's Sevilla side who are second, six points behind Real Madrid but with a game in hand.

There is the chance for Barcelona to climb to fourth – a Champions League place – with victory at the Sanchez Pizjuan, and Xavi said: "It is a huge opportunity."

The Blaugrana have taken 10 points from a possible 15 since Xavi became coach, stepping in after Ronald Koeman's tenure finally ended.

"It's not bad," he said of that points haul. "Sevilla have done very well. For me, they are an example to follow. Their philosophy and idea of ​​a club, their coach. They are role models.

"Sevilla are direct rivals. I think we are in a good moment. We are happy, I think we understand what we want."

Xavi reasonably felt his team should have done better than post a narrow 3-2 win over Elche on Saturday, given their overwhelming dominance of that game, and he says there is no room for error at this stage of the season.

"Tomorrow is another final and we will go there to win," he said.

"Our game model is to be daring, but Sevilla also want to do that. It will be an extraordinary match."

Carlo Ancelotti said Barcelona were not direct rivals to his Real Madrid team at present, when he spoke last week, and although there was plenty of logic behind that remark, Xavi's team could yet be a factor over the second half of the season.

"We are 16 points behind and that is a huge difference," said Xavi. "We don't rule out anything."

But Xavi concedes Sevilla are in an excellent position, with their weekend win over last season's champions Atletico Madrid confirming that.

Asked whether Sevilla could be champions this season, Xavi said: "Yes, it's clear. They were already a candidate last year.

"If they win tomorrow, they are three points behind the leaders in the middle of the season. Sevilla are a reality. 

"When you see how Lopetegui works, how [sporting director] Monchi works, for me they are an example to follow. They are candidates to win any competition they take part in."

Julen Lopetegui believes Barcelona finally have a clear vision for their future as his Sevilla side attempt to inflict one final blow of a terrible year for the struggling giants.

It has been a woefully grim 2021 for Barcelona, with the club having encountered dire financial problems that were a factor behind their greatest player, Lionel Messi, being forced to leave.

On the field, they won the Copa del Rey in April but have endured a torrid time in the Champions League and LaLiga, with another club legend, Ronald Koeman, losing his job as coach as a result.

The COVID-19 crisis has hit Barcelona hard, but out of the chaos of the last 12 months has risen an emerging group of young players who could save the club a fortune in transfer fees and point to a bright future on the pitch.

The likes of Pedro, Gavi, Ez Abde and Nico Gonzalez have come to the fore, at a time when Barcelona cannot rush to the cheque book to solve their problems.

With Xavi returning to the club as head coach, there are grounds for optimism again at Barcelona. Yet results continue to be mixed, and the perennial LaLiga title challengers are nowhere near that battle this time around as they head into their final game of the calendar year.

They travel to face a Sevilla side who sit second and are six points behind leaders Real Madrid with a game in hand.

Former Spain and Madrid boss Lopetegui would love his team to head into the winter break on a high, with this season one where they may not have to worry unduly about Barcelona entering the title race.

That could change if seventh-placed Barca win on Tuesday and shrink their deficit to Sevilla down to seven points, and Lopetegui has seen enough of Xavi's work-in-progress team to be wary of their threat.

Yet a 2-1 win at the weekend against last season's champions Atletico Madrid means Sevilla are on a high.

Lopetegui said in Monday's pre-game news conference: "Very recently we were playing one tough game and now another that is even tougher awaits us.

"We will measure ourselves against one of the best Barcelona [teams] for a long time.

"They have improved a lot, with players that you'd struggle to see at other teams, young but very good. They have got players back such as [Ousmane] Dembele, so we're expecting them to be very strong and with the influence of Xavi.

"We'll try to be fully recovered and prepare well, today we trained with 13 first-team players so we'll have to wait until tomorrow to make our final decisions."

Sevilla and Barcelona have both scored 28 goals in LaLiga this season, but the leakier defence has been that of the Catalan giants, shipping 21 in 17 games compared to Sevilla's league-best 12 conceded. Curiously, Barcelona have made just one error that has led to a goal, while Sevilla have made four.

These teams have scored their goals in strikingly different manners, with Sevilla having an even split between right-footed and left-footed goals among their haul – 11 of each – while Barcelona have scored just three left-footed goals and 20 right-footed, a sure sign that the Messi era has passed.

There has also been a major disparity between the finishing of each team. Barcelona have an expected goals (xG) score of 31.06 in LaLiga, but have fallen short of matching that, while Sevilla have impressively outperformed their xG total of 22.34 to stay on Madrid's coat-tails.

These teams like to have the ball, so something must give on Tuesday.

Barcelona have had 65.02 per cent of possession across their games this season, while Sevilla have had the ball 60.39 per cent of the time.

Injuries might be biting, but this is no time for searching for excuses, with Lopetegui insisting Barcelona's 3-2 win over Elche on Saturday did not fairly reflect the dominance of Xavi's team. Barcelona led the shot count 19-5 in that game, were 2.8 to 1 ahead on xG, and had 73.4 per cent of possession.

Lopetegui said: "You can see what Barcelona are looking for and they have the right players for that. They want the ball, they want width. They've got young, capable players, some of them start for Spain, while they've got top-class, experienced players. They have a lot of width, they're good at one-on-one situations, etc. Between the two areas we're going to have to do a lot of things right."

No spectators will be allowed in to watch India's tour of South Africa due to a soaring number of coronavirus cases.

Six days before the Test series starts at Supersport Park, Cricket South Africa (CSA) revealed matches will be staged behind closed doors in order to protect the players.

The Proteas and India will play three Tests and as many ODIs without fans in attendance.

A CSA statement said: "Cricket South Africa (CSA) has noted the interests of cricket fans and other stakeholders on the scheduling and the release of the details of ticket sales, in connection with the forthcoming India vs Proteas tour that is scheduled to begin in less than a week.

"Regrettably, CSA wishes to inform the most ardent fans of cricket as well as all sports lovers that owing to the increasing COVID cases around the world, and the fourth wave locally, the two cricketing bodies have taken a joint decision to protect the players and the tour by NOT making tickets available for the India vs Proteas offerings.

"This decision was taken in order to avoid any breaches that could compromise the tour from a COVID-risk perspective and to also maintain a hazard-free bubble environment."

Pholetsi Moseki, the CSA acting chief executive officer, said: "We acknowledge the interest expressed by the fans and other stakeholders on being able to return to stadiums and want to assure all cricket fans that this decision was not taken lightly, but was instead taken in the best interest of the game and in the interest of the health and safety of all patrons.

"Consequently, we urge all sport lovers to exercise absolute care, during these extraordinary times.

"I also wish to take this time to urge all South Africans to continue spreading the positive messages of VACCINATION, VACCINATION AND VACCINATION, because this is the only way that we can truly get our country back into its high economic activity, which will assist government to open up the economy and all its forms of economic activity, including allowing greater numbers of fans back into stadiums."

Juventus manager Massimiliano Allegri has dismissed agent Mino Raiola's suggestion that Matthijs de Ligt was ready to move on, saying the defender's next step is "to score goals".

Raiola claimed on Sunday that the centre-back was ready for a new step and suggested that the player shares the same view.

However, the 22-year-old has been performing well this term despite Juventus' struggles, with the Bianconeri seventh in Serie A, 12 points behind league leaders Inter.

Allegri was dismissive when asked about the agent's comments ahead of Juventus' clash with Cagliari on Tuesday, focusing instead on how the defender can improve and help the team.

"The step is to score goals tomorrow!" Allegri said in his pre-match press conference on Monday.

"I didn't hear the interview. I can only say that in [the 2-0 win over] Bologna he made two interventions as a great defender. He can still grow like all players."

De Ligt has been a regular fixture in Juve's defence this term, starting 13 times in 18 Serie A games and is becoming a dominant force in the air, competing for the most aerial duels per 90 minutes in the side (4.71) and winning 2.99 of them – also a club high.

Allegri is also still waiting for star forward Paolo Dybala to officially pen new terms, with the 28-year-old out of contract at the end of this season, and confirmed that the club plan to be active in the transfer window ahead of next season.

"I only know that there was a meeting the other day," Allegri continued. "I did not speak, I do not know the developments. It's an important contract.

"We have to work [in the transfer market], we have five months to do it. We have to be concentrated and be calm."

Joe Root does not believe Australia are "that much better" than England despite their dominant start to the Ashes.

England once again paid the price for a poor first-innings batting performance at Adelaide Oval, eventually succumbing to a 275-run defeat following prolonged resistance from Jos Buttler.

Buttler thwarted stand-in captain Steve Smith's side for over four hours as he made 26 off 207 balls before being trudging off after stepping on his stumps when facing Jhye Richardson (5-42), who claimed a maiden five-wicket Test haul.

Chris Woakes also made a battling 44, but England are 2-0 down and winless in 12 Test matches in Australia – their joint-longest run without a victory Down Under.

Captain Root says they have not done themselves justice in two emphatic defeats.

Root told reporters: "With the bat, we have got the ability. I don't think that Australia are that much better in these conditions as the scoreline suggests.

"I'm convinced we've got what we need to win Test matches over here but we're not going to if we keep missing chances and don't give ourselves an opportunity to get into the Test match with the bat.

"We've got to find ways of building those partnerships, getting in, making big contributions.

"That's something we'll have to do very well at Melbourne. I was absolutely gutted to get out last night. I should have been able to turn up today, put the pads on and lead by example, so I'm bitterly disappointed in myself."

Australia have now won all of their nine day-night Test matches, the only side to boast a 100 per cent winning record in such fixtures, while England are winless in their last four pink-ball outings since beating West Indies in 2017.

While Root bemoaned the lengths his bowlers settled on in Adelaide, the skipper reserved special praise for Buttler as he appreciated the tough task that lies ahead.

"Everyone is absolutely devastated for him, having had that mindset and that strength of character in what has been quite a difficult week for him," Root said of Buttler.

"I'm very proud of the way the guys fought today. The attitude and the desire, that's how we need to go about a whole match.

"But we can't just leave it to the last day to try and pull off an enormous feat like we had to do today.

"We've got three massive games now, with the Ashes on the line. If that's not motivation enough, I don’t know what is."

Geraint Thomas has committed his future to the INEOS Grenadiers after signing a new two-year deal, claiming he is "still super motivated".

The 35-year-old will now remain with the team until 2024, having joined when it was formed in 2010.

The Welshman insists that his passion for the sport has not wavered and reveals that he intends to make the most of the time he has left in his professional career.

"I'm still super motivated to work hard and train hard," Thomas said to the INEOS Grenadiers official website. "That's what I love doing. I still really enjoy riding my bike, pushing myself.

"When you can see the finish line of your professional sporting career, you want to make the most of it every day and make it all count."

Despite a difficult end to the last season, Thomas is looking forward to competing and believes he can still hold his own at the highest level.

"Obviously I had a tough end to 2021 but up until the crash at the Tour, I was in the best shape I’d been," Thomas continued. "I'm still very motivated to perform in the biggest races.

"I'll probably look at doing the Ardennes which I've never done properly. That's exciting and new, and hopefully, then go on the Tour to play a big role there.

"I'm super excited about the last few years of my career with the team. It's going to be fun - that’s the main thing.

"People keep asking me what my role will be and obviously I want to keep winning myself, but being a part of a winning team and having fun with some of my best mates is as important - ​​and to do that I'll need to be at my best."

Erling Haaland could still stay at Borussia Dortmund but "can wait for anybody" amid demand from Europe's top clubs, including Barcelona, according to the player's agent Mino Raiola.

Haaland signed for Dortmund from Salzburg after the Bundesliga side met his €20million release clause in December 2019 and has dominated the German top flight since his arrival.

The Norway international became the quickest player to 50 goals in the Bundesliga when he reached the milestone in his 50th appearance, and the youngest to do so at just 21, while only Robert Lewandowski (58) has scored more goals than Haaland (43) across all competitions in Europe's top-five leagues in 2021.

Haaland has also scored 30 Bundesliga goals this calendar year – a new Dortmund record, surpassing Lothar Emmerich (29 goals in 1966) and Pierre-Emerick Aubameyang (29 goals in 2015).

The 21-year-old is reported to have a €75million buy-out clause that will kick in at the end of the season, putting Europe's elite on high alert.

Dortmund chief executive Hans-Joachim Watzke expressed his belief on Sunday that Haaland should stay and Raiola has refused to rule that possibility out, though he did speculate on a potential move to Barcelona, whose financial issues may well mean a move has to be d

"Could Haaland wait for Barcelona? He can wait for anybody," Raiola said to NOS. "We don't have a pre-agreement with any club.

"We'll look for the best option for him and I can't rule out another year at Dortmund. Theoretically, that's still possible."

Barca are undergoing a difficult period under new head coach Xavi. They sit seventh in LaLiga and are already out of the Champions League, after the departure of Blaugrana legend Lionel Messi following the club's well-publicised financial difficulties.

Raiola, however, believes Barca will soon be back.

"Barcelona will always be one of the world's biggest clubs," Raiola added. "Even despite their current situation.

"In a year or two they'll be back. They have the power to find great economic agreements. They'll only need a year or two to get back."

Haaland has 13 goals in 11 Bundesliga appearances this term, while his tally increases to 19 across all competitions.

Belgium assistant coach Shaun Maloney has left his post to become manager of Hibernian.

Maloney was brought onto the coaching staff by Belgium boss Roberto Martinez – who managed him as a player at Wigan Athletic – in September 2018.

The former Scotland international has been part of the Red Devils set-up throughout their stay at the top of the FIFA World Rankings, and was Martinez's assistant during their run to the quarter-finals of Euro 2020.

The 38-year-old now leaves to take his first job as a manager, joining a Hibernian side that are seventh in the Scottish Premiership with 23 points from 18 games.

Rafael Nadal has tested positive for coronavirus on his return to Spain, leaving his participation at the Australian Open in doubt.

The 20-time major champion played at the Mubadala Tennis Championship in Abu Dhabi last weekend and declared his mission a success despite consecutive defeats on his return from a foot injury.

Indeed, Nadal had only competed in two matches since losing to Novak Djokovic in the French Open semi-finals in June before testing his long-term foot problem against Andy Murray and most recently Denis Shapovalov.

However, the 35-year-old's plans to feature in the Melbourne ATP 250 ahead of the Australian Open in early January have suffered a setback after he tested positive for COVID-19 upon landing in his home country on Monday.

Nadal revealed the news on Twitter as he posted: "I wanted to announce that on my return home after playing the Abu Dhabi tournament, I have tested positive for COVID in the PCR test that was performed on me when I arrived in Spain.

"Both in Kuwait and Abu Dhabi we passed controls every two days and all were negative, the last being on Friday and having the results on Saturday.

"I am having some unpleasant moments but I hope that I will improve little by little. I am now homebound and have reported the result to those who have been in contact with me.

"As a consequence of the situation, I have to have total flexibility with my calendar and I will analyse my options. I will keep you informed of any decisions about my future tournaments!"

Nadal was eyeing the Australian Open, which starts on January 17, as his first major comeback, though he earlier admitted his entry was not guaranteed as he evaluated his foot injury and physical fitness.

"I cannot guarantee Australia one hundred per cent, because I need to go home and see how the body responds after these days," Nadal told reporters on Saturday. 

"I have time to make a decision. At this point in my career, I need to go day by day, study each movement well.

"I have been able to show a competitive level against good players even without being in perfect condition. There are things to improve but looking at things with perspective it has been a positive tournament [in Abu Dhabi].

"The main objective is to be healthy enough to do the things that I need to do and aspire to the objectives that I have always had. The illusion and passion continue to exist."

The ATP Tour event in Melbourne, which would be Nadal's first such tournament since August, is due to start on January 3.

New Zealand will tour Pakistan twice in 2022-23 after the two boards reached an agreement in Dubai last month.

The Black Caps pulled out of a limited-overs series in Pakistan at the last minute due to a government security alert.

Kane Williamson's side will be back in the country to play two Tests and three ODIs from December next year to January 2023.

They will then return for five ODIs and as many Twenty20 Internationals in April 2023 to make up for not facing Pakistan this year.

New Zealand Cricket chief executive David White said: "Our respective chairmen, Ramiz Raja and Martin Snedden, had very fruitful and constructive discussions while in Dubai, further strengthening the bond between the two organisations It’s good to be going back."

Raja the Pakistan Cricket Board chairman, said: "I am pleased with the outcomes of our discussions and negotiations, and thank Martin Snedden and his board for their understanding and support.

"This reflects the strong, cordial and historic relations the two boards have, and reconfirms Pakistan's status as an important member of the cricket fraternity."

Steve Smith felt Mitchell Starc bowled "as well as he has for a long time" after Australia cruised to a 275-run victory over England in the second Ashes Test to take a 2-0 series lead.

The hosts posted a mammoth first-innings declaration total of 473-9 at the Adelaide Oval after Smith had stepped up as stand-in captain, following new Test skipper Pat Cummins coming into close contact with a positive COVID-19 case last Wednesday.

England could only muster 236 in response, despite 80 and 62 from Dawid Malan and captain Joe Root respectively, with Starc taking 4-37 from his 16 overs – only Nathan Lyon went at a lower economy (2.07).

Australia were again able to declare in the second innings, setting England an improbable 468 to win, before tearing through the tourists to leave six wickets required for victory on the final day.

Jos Buttler battled hard during a 207-ball stint but fell in unusual circumstances as he trod on his stumps going back to Starc, before Jhye Richardson fittingly sealed victory to complete his maiden five-wicket Test haul by removing James Anderson.

While Richardson managed a final-innings 5-42, Smith reserved special praise for Starc – who boasted 7-80 after two wickets in the second innings.

"Mitchell Starc bowled as well as he has for a long time, he led this attack well," Smith told reporters at the post-match presentation.

"He summed it up quickly that there wasn't a great deal of swing so he just wanted to bash a good length and hit some good areas - he did that as well as he has in his career.

"He looked in really good rhythm and I'm incredibly proud of the way he went about his business."

Australia have now won each of their last nine pink-ball Test matches, the only side with a perfect 100 per cent winning record, while England are winless in their last four day-night fixtures since last defeating West Indies in August 2017.

Smith, who fell seven short of a century in the first innings, was captaining for the first time since the 2018 ball-tampering scandal in Newlands and enjoyed his return to the helm, while hailing the performance of some England batters.

He added: "We weren't nervous. They showed some good resistance and fight. Jos played extremely well - it was an innings we haven't seen from him before, he's usually a bit of a dasher. He showed good fight, as well as [Chris] Woakes and [Ollie] Robinson.

"We felt there was time left and all it would take was a couple of good balls.

"I had fun this week as captain and did enjoy it. The guys played really well. We were able to control the game from the first day as Marnus [Labuschagne] and Davey [Warner] set it up with their partnership.

"So we were able to declare when we wanted and bowl where we wanted to bowl."

Joe Root says the England bowlers must be "braver" after Australia won the second Ashes Test at the Adelaide Oval by 275 runs to take a 2-0 series lead.

Jos Buttler made 26 from 207 balls before he stepped back onto his own wickets and Chris Woakes top-scored with 44 as the tourists put up an admirable fight on the final day.

However, it was always likely to prove fruitless and they were eventually bowled out for 192 in the final session.

Jhye Richardson (5-42) claimed a maiden five-wicket Test haul on his Ashes debut, showing Australia's strength in depth in their bowling ranks in the absence of Pat Cummins and Josh Hazlewood.

Cummins is set to return to captain Australia for the Boxing Day Test in Melbourne after missing out in Adelaide due to being a close contact of a positive COVID-19 case.

England's' shortcomings with the bat have been plain to see, but skipper Root wants to see the bowlers change their approach to give them a chance of getting back into the series.

Asked about England's plans, he said: "I think when you look at ball in hand in particular, I don't think we've bowled the right lengths if we're being brutally honest, we needed to bowl fuller.

"As soon as we did in that second innings, we created so many chances and we made it hard work. We need to do that more, we need to get the ball up there, be a bit braver because when we do we make life difficult.

"That's one of the frustrating things, we did that four years ago and we didn't learn from it – we've made mistakes throughout the game that we made last week, whether it be no-balls, missed chances, we just have to be better. We have to learn those lessons quickly ahead of next week."

England will ponder making changes in Melbourne, with fast bowler Mark Wood expected to return.

Root said during the post-match presentation: "Of course someone like Woody, he's always going to offer something, that extra bit of pace he has and hopefully he'll be raring to go for the rest of the series."

Despite England having a mountain to climb, Root believes they can pull off a remarkable fightback and challenged his fellow batters to step up.

Asked if he believes they are capable of winning the series, he said: "Absolutely, you have to be. I think, I'm convinced we have got what we need to win over here, we just need to be better and we can't keep making the same mistakes.

"Guys need to get themselves in, get past that first 20-ball period and then get greedy.

"We need to leave better on occasions as well and manage certain passages of play better, but we're more than capable of doing that and we've shown it in small pockets that we can we've just got to do it for longer, and as I said, do better."
