Lionel Messi has been tipped to leave Barcelona for either Manchester City or Paris Saint-Germain.

Barca have also been linked with Borussia Dortmund's Erling Haaland.

But Haaland could reportedly unlock Messi's future.

TOP STORY – HAALAND TO CITY MEANS BARCA STAY FOR MESSI?

Borussia Dortmund star Erling Haaland could hold the key to Lionel Messi's future at Barcelona, according to the front page of Thursday's Diario AS.

Haaland is a player in demand, linked with Barca, Manchester City, Real Madrid, Manchester United, Chelsea, Liverpool, Juventus and Paris Saint-Germain.

City have been tipped to sign Messi, but should they step up their pursuit of Haaland, the Premier League leaders could reportedly drop their interest in the Barca captain.

ROUND-UP

- Mundo Deportivo says new Barca president Joan Laporta is preparing a contract renewal for Messi, who is set to become a free agent at season's end.

- Bayern Munich are eyeing a move for Tottenham star Son Heung-min, claims Football Insider. Son has reportedly been offered a bumper new contract by Spurs, but the former Bayer Leverkusen forward is wanted in Munich.

- Sporting CP's Joao Palhinha, Borussia Monchengladbach star Denis Zakaria and Sander Berge of Sheffield United are on the list of midfielders to replace City veteran Fernandinho, reports A Bola.

- Gazzetta dello Sport says Juventus and Barca are interested in Milan captain Alessio Romagnoli. The Italy defender is out of contract in 2022 and is reportedly seeking a €6million-a-year contract.

- Napoli are eyeing Lazio head coach Simone Inzaghi and sporting director Igli Tare, claims Radio Kiss Kiss Napoli. Gennaro Gattuso has been tipped to leave Napoli at the end of the season, with ex-Juve boss Massimiliano Allegri, Luciano Spalletti and Hellas Verona's Ivan Juric among the possible replacements. But Lazio duo Inzaghi and Tare are being monitored to replace Gattuso and Cristiano Giuntoli in Naples.

- United are interested in Lille defender Sven Botman, according to Fabrizio Romano. Sevilla star Jules Kounde has been on United's radar but the club's asking price of €80m (£68m) is too steep.

- Romano also says there is no agreement with United and Paul Pogba over a new contract. Pogba has been linked with former club Juve, Madrid and PSG.

Manchester City star Sergio Aguero is reportedly wanted by Barcelona.

Aguero's future at City is uncertain with the 32-year-old coming out of contract at the end of the season.

And the forward is unsurprisingly wanted by Europe's biggest clubs.

TOP STORY – BARCELONA WANT AGUERO

Barcelona are eyeing Manchester City forward Sergio Aguero, according to The Sun.

Aguero has also been linked to Paris Saint-Germain as City's all-time leading goalscorer entered the final six months of his contract.

The Argentina international has scored two goals in nine games this season.

ROUND-UP

- Staying at Barcelona and Eric Garcia looks set to join the club from City. The cover of Mundo Deportivo says Garcia is poised to move to Barca in January in a deal worth €5million (£4.5m) plus variables.

- Also facing an uncertain future is Fernandinho. The Telegraph reports Fernandinho is undecided about his future, with the City man having offers from South America.

- Matteo Guendouzi is set to see out his loan spell at Hertha Berlin. Fabrizio Romano says the midfielder will not return to Arsenal in January, with the Bundesliga club wanting him to stay until season's end.

- Wolves seem unlikely to sign a forward in January. The Mirror claims they have aborted interested in Liverpool striker Divock Origi and Chelsea's Olivier Giroud.

- With Frank Lampard under pressure at the helm of Chelsea, help could be incoming. Sky Sports reports Chelsea owner Roman Abramovich is considering bringing back former manager Avram Grant to work with Lampard.

Sergio Aguero's mood is "better than ever" as he tentatively nears the end of an injury nightmare, according to Manchester City manager Pep Guardiola.

Guardiola confirmed City's all-time top scorer will start Sunday's FA Cup third-round tie against Birmingham City at the Etihad Stadium as he looks to put the after-effects of meniscus surgery behind him.

Aguero underwent an operation in June and has been forced to manage ongoing discomfort in the joint since a hamstring injury at West Ham curtailed his initial return in October.

Despite being ravaged by a coronavirus outbreak among their squad, City head into the weekend buoyed by their two finest performances of the season - a swashbuckling 3-1 win over Chelsea preceding a 2-0 win against rivals Manchester United in the semi-finals of the EFL Cup.

Four minutes from the bench at Stamford Bridge was the sum of Aguero's action across the those games, as he was an unused substitute at Old Trafford.

Nevertheless, his goalscoring prowess has been an obvious miss across the course of the campaign. In their most recent title-winning season, City averaged 2.6 goals per game in the Premier League with Aguero in the side.

That has fallen to 1.6 in all matches this time around, with a win percentage of 53.9 per cent, set against 84.8 with Aguero in harness two seasons ago. Shots per 90 minutes are also down from 18.1 to 15.6 when the two data sets are compared.

"Just look at the numbers, the quality he has in the box, Sergio is unique," Guardiola told a pre-match news conference.

"He has a tough, tough injury. The important thing is his mood is exceptional, I would say better than ever.

"It's important that the feeling, the last two weeks, his knee's reaction was really good after training. This is the best news we can have.

"He’s going to start, the minutes his performance level or knee will dictate. What's important is good quality minutes, as much as possible, we start from the beginning and after we'll see what happens.

"It will be great to have Sergio fit. He’s so optimistic. He says 'I will score goals' and that is the most important thing."

Aguero is out of contract at the end of the season, as is fellow fans' favourite Fernandinho.

The 35-year-old Brazil international has returned to his customary central midfield position this season, having deputised at centre-back for much of last, and completed the scoring with a sweetly struck volley against United in midweek.

Following the departure of David Silva over the close season, Fernandinho has stepped up as club captain and impressed Guardiola greatly with his leadership skills.

"With the players in this part of the season, everything is open," Guardiola said, when discussing the prospect of the veteran earning a fresh deal.

"I am more than impressed with the first captain role of Fernandinho, he is leading in an exceptional way. In the good moments and the bad, bad moments.

"If everyone can take an example of what he has done so far, the team will be stronger."

Pressed for examples of how the quietly spoken star commands the dressing room, Guardiola replied: "How he talks with his mates, how he talks with my assistant coach, before the game, at half-time.

"Not just talking to players about football matters, in life, how to behave in training, every single day. He's the first who proves that he's able to do it.

"That's why he goes to Old Trafford, plays holding midfielder there. It was not easy for Bruno Fernandes to control him.

"At the beginning of the season he stepped forward and showed how to be a captain."

City will have Ederson, Ferran Torres and Tommy Doyle available for selection once more, provided they returned negative COVID-19 tests on Friday.

The trio tested positive ahead of the postponed Premier League match at Everton on December 28.

Pep Guardiola dedicated Manchester City's 2-0 EFL Cup semi-final win over Manchester United to club great Colin Bell.

Former City and England midfielder Bell died on Tuesday after a short illness, aged 74.

City's players wore retro shirts bearing Bell's number eight before kick-off at Old Trafford, where a minute's silence was observed.

When the action got underway, an absorbing contest at odds with a dour 0-0 draw between the sides in the Premier League last month ensued, with City prevailing thanks to second-half goals from John Stones and Fernandinho.

"It's for him and, of course, for his family," Guardiola told Sky Sports in a post-match interview which he conducted wearing a t-shirt featuring Bell's likeness.

"This person helped to build something special for this club that doesn't have many, many trophies in the cabinet. But that is not important.

"What is important is the legacy that players provide from the past and some of these players in the future. That is the club we have now.

"It is an incredible victory for us to beat United away and be in another final.

"But especially today, it is for him. Absolutely."

City might be considered to have "many, many" EFL Cups if they are able to claim a fourth in a row against Tottenham in April's final.

Guardiola praised his players for a notable upturn in form of late after they followed up Sunday's swashbuckling 3-1 win over Chelsea in impressive fashion, despite Scott Carson and Cole Palmer taking the number of positive COVID-19 tests among his squad to eight since Christmas Day.

"You are frustrated when you play bad. When the team don't run, don't help, don't celebrate every defensive action," he said, rejecting the suggestion he was unhappy after a goalless first half.

"The team is ready. That is why we came here with an outstanding performance.

"We suffered a little bit in the second half because we were tired after the game at Stamford Bridge. They had two more days off to rest but when a team has the mentality to do it we achieve something incredible.

"I know the Carabao Cup is not the Champions League but four times in a row reaching the final is incredible. I am so impressed by the quality of this team."

As Manchester City's players huddled around the centre circle in number eight shirts to pay a poignant pre-match tribute to Colin Bell, it occurred a Pep Guardiola team might never have been so fittingly dressed.

England international Bell, widely revered as the finest player in City's history, passed away after a short illness on the eve Wednesday's 2-0 Manchester derby win the semi-final of the EFL Cup.

Bell, according to the loud and often repeated refrain of the Kippax Stand at City's old Maine Road home, was the greatest inside forward that the world had ever seen.

A technically gifted all-round midfielder, somehow simultaneously graceful and powerful, Bell thrived in those dangerous pockets between winger and centre-forward to cause maximum damage in Joe Mercer and Malcolm Allison's celebrated City teams of the late 1960s and early 1970s.

The inside forward had long gone out of fashion before Pep Guardiola ushered in his era of "free eights". From Xavi and Iniesta, through Thiago Alcantara and Toni Kroos to David Silva and Kevin De Bruyne, City's former Barcelona and Bayern Munich boss delights in filling his side with such players.

During Sunday's swaggering 3-1 win over Chelsea, De Bruyne was joined in the line-up by Phil Foden, Ilkay Gundogan and Bernardo Silva. That quartet of playmakers probably would have resumed duties together at Old Trafford had Silva not been suspended.

After paying tribute to City's eternal eight, Guardiola's team of number eights got to work. Where the league fixture on this ground a month ago was as stodgy as the pitches Bell graced in his heyday, the pop and fizz to the early passing was much more in "Nijinsky's" image.
