Having already lost key midfielders Paul Pogba and Scott McTominay to serious injuries, Manchester United now face the prospect of being without top scorer Marcus Rashford for the most important part of the season.
The England international aggravated a back injury during a second-half cameo against Wolves in the FA Cup third-round replay victory, and after Ole Gunnar Solskjaer downplayed United's worries, it was later confirmed to be much more serious than first thought.
Reports began to emerge during United's 2-0 defeat to Liverpool that Rashford had actually been playing through the pain and Solskjaer confirmed he suffered a double stress fracture against Wolves, meaning he could potentially be out for three months.
As such, Solskjaer acknowledged United might be forced into seeking "short-term" solutions in the transfer market, with Mason Greenwood and Anthony Martial their only recognisable forwards.
Below, we highlight some potential options.
Paco Alcacer (Borussia Dortmund)
Spain international Alcacer has had a peculiar time at Dortmund. He managed to score 18 times in the Bundesliga last season even though he only started 11 matches, while he has five top-flight goals this term despite only six of his 11 appearances coming as a starter. While he is a completely different type of forward to Rashford, he does represent a kind of attacker United simply do not have, in that he is a poacher. Following the arrival of Erling Haaland – apparently a target of Solskjaer's before he joined BVB – Alcacer might be attainable.
Edinson Cavani (Paris Saint-Germain)
After falling out of favour at PSG, Uruguay striker Cavani has asked to leave before his contract expires at the end of the season, with Atletico Madrid and others said to be interested. A proven goalscorer and immensely experienced, Cavani would certainly provide United with a focal point they can aim for and play off – though his wages are not insignificant and he might not be entirely suited to counter-attacking football.
Mariano Diaz (Real Madrid)
Since returning to Madrid in 2018, Mariano has had a difficult time of it. Niggling injuries have impacted his availability and he has unsurprisingly struggled to make a telling contribution as a result. He is yet to feature in LaLiga this term, having fallen well down the pecking order – but that is not to say Mariano is a poor player. Quick, technically good and certainly capable of finding the net, he is perhaps rather more suited to United's style of play than Alcacer or Cavani.
Cedric Bakambu (Beijing Guoan)
In 2018, Bakambu cost Beijing Guoan €40million, the release fee in his contract with previous club Villarreal. The DR Congo striker had enjoyed a solid three-year spell at the Yellow Submarine, with his combination of athleticism, ability on the ball and finishing making him standout as a potential target for bigger clubs. He has continued to score on a regular basis in China and is starting to attract interest from Europe again, with Arsenal and Atletico Madrid apparently keeping tabs on him. United could do a lot worse than the former France youth international.
Promote from the academy
Solskjaer certainly can't be accused of neglecting the young talents coming through at the club. If he was to promote from within, rather than dip into the transfer market, D'Mani Mellor and Largie Ramazani would likely be the two frontrunners. Mellor is a 19-year-old forward who likes to drop deep and engage in sharp link-up play with his back to goal, while he is also a capable dribbler. Ramazani, 18, often operates a little more from wider positions, but the Belgium youth international has impressed for United's Under-23s this term with nine goals in 13 league appearances. Excellent on the ball and a possessor of explosive pace, Ramazani certainly seems to fit the mould Solskjaer likes his forwards to be.
