The 2021-22 season may still be ongoing at international level, but Premier League and Ligue 1 clubs can officially register new signings for the next campaign following the opening of the transfer window on Friday.
Teams in LaLiga, Serie A and the Bundesliga must wait until July 1 for their business to go through – though that is not to say preparations are not already in full swing behind the scenes.
Indeed, a number of big deals are already in place and waiting to get the seal of approval, with Antonio Rudiger heading to Real Madrid and Karim Adeyemi brought in by Borussia Dortmund to replace Manchester City-bound Erling Haaland, while others – Darwin Nunez to Liverpool and Aurelien Tchouameni to Madrid – appear to be all-but complete.
One transfer saga came to an end before the window even officially opened, meanwhile, with Kylian Mbappe confirming that he is staying put at Paris Saint-Germain, despite strong interest from Madrid.
For others, there are weeks of uncertainty ahead. Having already picked out the big-name free agents up for grabs this window, Stats Perform looks at the transfer sagas that are likely to rumble on for a little while longer yet.
Player: Robert Lewandowski
Current club: Bayern Munich
Rumoured suitors: Barcelona, Real Madrid
While the futures of Mbappe and Haaland have already been resolved, arguably the world's best striker in Lewandowski is seeking pastures new after recently declaring that his time at Bayern "has come to an end" – even if the German champions do not quite see it that way.
The Poland international still has 12 months to run on his contract and Bayern are understandably reluctant to sell, even if that means forgoing a transfer fee in a year's time, making things particularly difficult for Barcelona, who are the rumoured frontrunners for his signature.
He was once again the hottest striker across Europe's top five leagues in 2021-22 when taking all competitions into account, the 33-year-old scoring 50 goals in 46 games for Bayern in what was his second-best goalscoring campaign across eight years in Bavaria, behind only the 55 netted in 2019-20.
Player: Sadio Mane
Current club: Liverpool
Rumoured suitors: Real Madrid
Whether it is to replace wantaway Lewandowski or to play alongside the prolific striker, Bayern are seemingly intent on bringing Liverpool and Senegal forward Mane to the Allianz Arena.
Bayern are reported to have had a second bid of €35.3million (£30m) turned down by Liverpool earlier this week, with the ball very much in the Reds' court – just like it is with the Bavarians and Lewandowski.
Mane would be a huge loss to Liverpool, having scored 90 goals in 196 Premier League appearances since joining at the start of 2016-17 – only Jamie Vardy (104), team-mate Mohamed Salah (118) and Harry Kane (134) have more – explaining their desire to snap up Nunez from Benfica.
Player: Gabriel Jesus
Current club: Manchester City
Rumoured suitors: Arsenal, Chelsea, Tottenham, Real Madrid
Manchester City striker Jesus may just about be the most in-demand player up for grabs this window, with his agent confirming as many as seven clubs are interested in signing the Brazil international.
Arsenal are the only known team to be in discussions with Jesus' camp, though they are expected to face interest from the likes of rivals Tottenham and Chelsea, as well as reigning European and Spanish champions Madrid.
The stats reflect exactly why Jesus is so highly regarded – albeit not by City following the arrival of Haaland – as he has scored or assisted in 57 per cent of matches he has started in the Premier League, a figure bettered only by Salah (62 per cent), Thierry Henry (61 per cent) and City legend Sergio Aguero (60 per cent) among those to have started at least 10 games.
Player: Frenkie de Jong
Current club: Barcelona
Rumoured suitors: Manchester United
De Jong has not quite been able to match expectations at Barcelona since arriving from Ajax in a big-money deal two years ago, which the midfielder has regularly put down to being used out of position in central midfield.
The arrival of the Netherlands international's former Ajax boss Erik ten Hag at United has only intensified speculation that he could be on his way out of Camp Nou, with Barca themselves needing to offload players if they are to seriously strengthen elsewhere.
De Jong will leave a void to be filled if he does move on, though, as Sergio Busquets (51) was the only Barca outfielder to feature in more games in the 2021-22 campaign than the 25-year-old (47 apps).
Player: Christopher Nkunku
Current club: RB Leipzig
Rumoured suitors: Chelsea, Liverpool, Manchester United, Real Madrid
Nkunku well and truly burst onto the scene in the 2021-22 campaign with a combined 51 goals and assists in 52 games for Leipzig across all competitions, meaning he near enough directly contributed to a goal per game.
Only Europe's absolute elite players, Lewandowski (56 goal involvements), Benzema (59) and Mbappe (60), outperformed Nkunku in that regard, making links with Europe's top clubs unsurprising.
Still aged only 24, the four-cap France international may well be a Ballon d'Or winner in waiting if his trajectory over the past couple of seasons is anything to go by. But with two years to run on his Leipzig contract, it will take a huge sum for the Bundesliga side to even consider cashing in.
