If United convinced Borussia Dortmund to part with Mats Hummels could they retain their title?
In the end Maraoune Fellaini was the only noticeable player to arrive in the entrance of Old Trafford - much to the disappointment of the United faithful.
Many a United fan believes the club need to bring in an attacking midfielder to link the attack and midfield - but I would argue they have now found that with Adnan Januzaj - while Shinji Kagawa still has it in him, as does Wayne Rooney.
The fact is, with this group of attacking talent, United will always score goals.
The only bizarre fact is they have started leaking them like a sieve.
Nemanja Vidic and Rio Ferdinand both continue to struggle with injury issues, while Jonny Evans, Phil Jones and Chris Smalling have had mixed seasons.
One thing that is for sure, United conceding 13 goals already this season is certainly not something they would have considered at the beginning of the campaign.
Surely they need a new centre-back anyway, regardless of form? Jones Is better in the midfield, while Smalling and Evans cannot do it themselves. Ferdinand and Vidic’s contracts both expire at the end of the season, and neither is a spring chicken.
A cultured, strong and young defender is surely an area in which they should be considering adding a player.
Is Mats Hummels that man?
It would be an ambitious move, and the German international did recently rule out a move to Barcelona.
But Dortmund could find themselves out of the Champions League by the New Year, and that would mean Europa League football.
It may not bother him much at all, but he may be looking for something fresh.
He is absolutely the perfect mould for a modern day central defender, suited excellently for the Premier League.
In fact he is a lot like Rio Ferdinand in style, accept when Rio was 24-years-old.
The price would be monumental, Die Schwarzgelben would be looking for at least £30 million - in fact it would likely be nearer to the £40 million mark.
But for a player that would be the focal point of the United defence for the next ten years - it would be a sound, and potentially title winning investment.
