Kylian Mbappe remained at Paris Saint-Germain beyond the end of the transfer window, but his long-term future may not lie in the French capital.
The World Cup winner is a free agent at the end of the season and is reportedly ready to move.
Real Madrid, who bid for Mbappe at the start of this campaign, appear his most likely destination, but far less predictable is his potential replacement at PSG.
The Ligue 1 giants have months to plan their next move, so Stats Perform breaks down the possible options to fill Mbappe's big boots.
Borussia Dortmund remained firm in their stance of keeping hold of Haaland in the most recent transfer window, despite some heavyweight clubs reportedly showing an interest as deadline day approached. That interest will only increase in 2022 as the Norwegian has a widely reported €75million release clause that comes into effect at the end of the season.
Landing Haaland would mean PSG replacing one of the world's best young goal-getters with another player of equivalent standing, the 21-year-old having scored 63 goals in 64 games since his Dortmund debut in January 2020, compared to 54 in 66 matches for Mbappe in all competitions.
Following Manchester City's failed pursuit of his signature, Kane announced towards the end of the transfer window he was staying put at Tottenham. City's loss – assuming they are not prepared to go back in for the England captain, as Pep Guardiola recently hinted at – could be PSG's gain.
A reunion with his former Spurs boss Mauricio Pochettino in Paris would appear to make a lot of sense, if PSG could stump up the huge fee that Tottenham would still insist upon next year. Having finished as Premier League top scorer in three separate campaigns – one of only three players to do so along with Thierry Henry (four times) and Alan Shearer – he will feel he deserves his move to an elite club that can challenge for major honours.
Lionel Messi and Pochettino will know all about the qualities of their fellow Argentinian, who has shone brighter by the season for Inter over the past three years. At the age of 24 and having been linked with the likes of Barcelona, Tottenham and Man City, Martinez is reportedly on the brink of signing a new deal with the reigning Serie A champions, which could make PSG's life a lot more difficult when it comes to any negotiations.
Whether he is quite of the level to take the place of Mbappe is debatable, and this year should prove telling, with Martinez facing a greater onus to score heavily after Romelu Lukaku's departure from Inter. He has one goal in one appearance this term, a goal-per-game return he will be looking to maintain over the course of 2021-22.
While the likes of Messi, Lukaku, Cristiano Ronaldo and Antoine Griezmann all changed clubs during the transfer window, Lewandowski stayed put at Bayern Munich despite suggestions he was seeking a new challenge elsewhere. With Bayern under no pressure to sell, and the prolific striker having two seasons to run on his contract, a move away this year never seemed a realistic prospect.
But it will be a different matter in nine months' time and PSG could do a lot worse than go all out for the Poland international, even if he is now 33 years of age. Having last term scored 41 times in the Bundesliga – breaking Gerd Muller's single-season record – Lewandowski has maintained his lofty standards in the opening weeks of the new campaign with 10 goals in his first six matches for club and country, going a long way to strengthening his argument of being the best out-and-out striker around.
Salah is in an identical position to Lewandowski insofar as the Egypt forward will be about to enter the final 12 months of his contract come the end of the campaign. After previously flirting with LaLiga giants Barcelona and Real Madrid, PSG have their work cut out persuading Salah to make the move to Ligue 1 instead.
Should they manage that, though, they will have one of Europe's top attacking talents from the past four years. Indeed, since joining Liverpool from Roma ahead of the 2017-18 season, the 29-year-old's tally of 97 goals has been bettered by only four players in Europe's top five leagues: Ciro Immobile (104), Ronaldo (107), Messi (125) and Lewandowski (131).
The 21-year-old Serbian came of age in Serie A in the 2020-21 campaign, scoring 21 of Fiorentina's 47 goals to finish fourth in the league's scoring charts and earn the division's Under-23 MVP award.
While not quite in the same category as some of the others on this list, Vlahovic may well be the hottest property around come next June as he already has three goals in three appearances for his club in all competitions this term.
Neymar's Brazil strike partner is another who has been touted for a move to Paris since Madrid launched their Mbappe offensive last month. Everton made clear that they were not interested in selling Richarlison in August, but that may change should PSG be prepared to spend big once again.
Now into his fourth season at Goodison Park, Richarlison has yet to score more than 15 Premier League goals in a campaign for the Toffees, but at the age of 24, he has gained huge experience and was a key member of Brazil's recent Olympic gold medal-winning squad in Tokyo.
