Barcelona have received one of their biggest boosts in their transfer planning as it emerged that Jose Mourinho's Manchester United will not join a bidding war for Atletico Madrid striker Antoine Griezmann. The Catalan club are still looking at ways to improve their squad in the upcoming transfer windows and one option the technical staff have picked out is Griezmann, who they were previously linked to after Neymar left for Paris Saint-Germain. Since then, Griezmann's reluctance to leave Atletico Madrid whilst they were under a transfer ban made a deal impossible. Nor would it have been easy to bring him to Camp Nou if he had been ready to move, as Manchester United were keen on the French international last summer. In fact, the situation in the summer was matter of United being more interested than Mourinho. Mourinho likes the idea of having Griezmann in his side, but was not convinced by the price at which he would come, unlike many other staff behind the scenes.
