#2 Antoine Griezmann
Antoine Griezmann looked set to join the Red Devils in the summer when United were prepared to trigger his release clause of €100 million. They move fell through because of Atletico's transfer ban. Griezmann penned down a new deal with Atletico, as a result.
However, his release clause still stands at €100 million, which could be inviting and cheap for such a quality player in the current market scenario. Jose would be looking to bolster his attacking options ahead of a crucial season where United will be challenging for every trophy.
