The Spanish midfielder could leave Atletico Madrid for around £50 million.
David Moyes still believes his side will mount a title challenge in the New Year and in their current form, you have to agree it is a possibility.
But they won’t do it without some recruits coming through the door in January - in particular in the midfield area.
In the summer they moved for Ander Herrera, Cesc Fabregas and Thiago Alcantara - all deals that never reached completion.
Now they are being linked with yet another Spaniard - Atletico Madrid midfielder Koke.
The 21-year-old has come of age in the centre of the park for Los Colchoneros and is now knocking on the door of the Spanish national team - as Madrid fight Barcelona for the La Liga title.
Reports have linked United with a potential £30 million bid for the player in January - but if they pay more they can take the decision making entirely out of his current club’s hands.
It has been reported in AS today that he has a release clause in his current contract - believed to be €60 million.
The prevalence of a release fee is no surprise - as most Spanish teams adopt this policy.
So is he worth it?
United splurging around £50 million on one player is certainly unprecedented and would be out of character for the usually frugal David Moyes.
The fact remains that Koke is still widely untested. This is only his second season as a first-team regular in the Atletico team - and while he has been impressive, it is a lot of money to spend on one unknown quantity.
Hopefully Atletico are willing to do business below the release fee - as at that price, United will not be signing Koke in January.
