Both Clubs Atletico Madrid and Manchester United do agree that the French striker Antoine Greizmann could very well be joining the Spanish giants Barcelona instead of joining Manchester United. He was actually supposed to have left Atletico Madrid in the summer transfer window, but sadly F.I.F.A had a ban put in place against Atletico Madrid. The club was banned from buying any footballer till 1/1/2018. Yes they could buy a player from any club, but he would not be able to be registered with F.I.F.A , and as he was not registered he would not be allowed to play for Atletico Madrid. A few years ago Barcelona were banned from buying any footballers, but they still brought two footballers Arda Turan and Alexi Vidal., both collected their weekly wages from Barcelona , but did not play a single match. As the ban is lifted on 1/1/2018 Antoine Greizmann could very well be a Barcelona player.
