Manchester United have plenty of issues to solve ahead of next season, no matter where they end up in 2021-22.
It seems certain that Ralf Rangnick will not be in charge, with Mauricio Pochettino among the favourites to take over, though the former RB Leipzig boss is set to move into a consultancy role at Old Trafford, and certainly has an eye for picking a player.
United have requirements in central midfield, regardless of whether Paul Pogba stays or goes, but based on current evidence, they also need a striker.
Their problems up top have come back to bite them in recent games. In fact, against Watford last time out, United had 22 shots, finishing with an expected goals (xG) of 2.7, yet drew 0-0 at Old Trafford. Putting away chances has been a major area of concern.
Cristiano Ronaldo returned to the club at the end of the August transfer window, and while he has contributed 15 goals in all competitions, it could easily be argued that United's all-round play has taken a hit since the 37-year-old's homecoming.
Edinson Cavani has featured only sporadically this season and, like Ronaldo, is approaching the twilight of a glistening career. Both players may well not be at United heading into 2022-23.
Anthony Martial is out on loan at Sevilla, with his United future looking rather bleak. Marcus Rashford, meanwhile, seems to lack the clinical nature to lead a title-challenging line.
The last time United went out and signed a striker at their peak was the season in which they last won the Premier League – Robin van Persie proving the difference in Alex Ferguson's last campaign in charge.
On Sunday, United face rivals Manchester City. A team that has perfected playing without a recognised number nine.
That is testament to Pep Guardiola's genius, but it has proved that it can be done. So, looking further down the line, who is the forward that United need?
Here, Stats Perform assesses some standout options.
Harry Kane (Tottenham)
Kane has long been linked with a move to Manchester, to both sides of the red-blue divide. It appeared City would bring the England captain north last year, yet Tottenham refused to budge, and it would seem that particular ship has sailed – Kane turns 29 this year and, with Erling Haaland's reported €75million (£62.1m) release clause, City are reportedly prioritising the Borussia Dortmund star.
That could that leave the door open for Kane to rock up at Old Trafford instead, especially if the option of linking up with Pochettino is on the table.
It has been a tough season for Kane by his lofty standards, though his brilliant performances against City and Leeds United in recent weeks showed the player that was at the top of his game last season is still there.
Alexander Isak (Real Sociedad)
Taking Kylian Mbappe and Haaland out of the equation, United might still look at the younger end of the spectrum. In that regard, Real Sociedad's Isak may fit the bill.
Isak scored 17 LaLiga goals last season and, while he has not reached quite the same heights in 2021-22, at 22 he is definitely one for the future. His tally of eight goals across all competitions is disappointing, though when looking at expected goals on target (xGOT) – a tool that can quantify the quality of a player's finishing – Isak is at 12.2 for the season, suggesting that the placement of his shots should have resulted in more goals.
Patrik Schick (Bayer Leverkusen)
While not among the elite, if United are looking for a goalscorer then they could do worse than Schick, who has carried over his fine form from Euro 2020 into this season, scoring 20 goals in 24 matches for Bayer Leverkusen, striking on average every 84 minutes, which is the third-best minutes per goal ratio of strikers in Europe's top five leagues to have already netted at least 20 goals in all competitions, after Haaland and Robert Lewandowski (more on him later).
Schick has already had something of a nomadic career but at 26 is about to enter his prime years. His shot conversion rate of 28.17 is superb, ranking fourth out of players from the Premier League, Bundesliga, Serie A, LaLiga and Ligue 1 to have scored at least 10 times.
The Czech's xGOT of 16.1, minus his xG of 14.4, gives him a shooting goals added (sga) figure of +1.7, meaning he is executing better quality shots than the quality of the chances he has attempted shots from. However, in contrast to Isak, he may also have benefited from goalkeepers failing to keep out attempts they would be expected to.
Lautaro Martinez (Inter)
One player who is among Europe's elite forwards is Inter's Martinez. The Argentine struck up a fearsome partnership with Romelu Lukaku in 2019-20 and 2020-21, and he has scored 12 goals already this season.
Martinez's aggression and pace could make him an ideal frontman for the Premier League, though his finishing can be erratic (he has had 102 attempts this season but has a conversion rate of just 11.76 per cent), while he has also underperformed his xG (17.1). The Argentine did only sign a new Inter contract last year, so he would be hard to prise away.
Robert Lewandowski (Bayern)
Before disregarding the option of Lewandowski as fantasy, take into account that he has not yet signed a new deal with Bayern Munich. The 33-year-old's contract expires in 2023.
Lewandowski is undoubtedly the best out-and-out striker in world football right now and, if Ronaldo and Cavani were to leave, United might prefer to go with experience.
Not that experience is all Lewandowski would offer. He will go down as one of the best to grace the game and has 39 goals in 33 appearances this season, slightly overperforming his xG (37.6) in the process. He nets on average every 73 minutes and, like Van Persie a decade ago, would surely transform United into title contenders. That being said, the same was also said about Ronaldo.
Joao Felix (Atletico Madrid)
Something of a wildcard option, Joao Felix is not the typical striker, but if United were to go down a Guardiola-inspired false nine route, then the former Benfica boy wonder might be the perfect fit.
It would be harsh to say Joao Felix has been a failure at Atletico Madrid, but it is fair to suggest he has not been a rip-roaring success under Diego Simeone either.
Yet the 22-year-old has shown flashes of brilliance. Indeed, he outshone compatriot Ronaldo in United's recent Champions League draw with Atleti and with the tactical nous he is sure to have got from Simeone, it would be intriguing to see him at Old Trafford.
