Paris Saint-Germain's Angel Di Maria said that he would have no problem playing for Barcelona if the opportunity presents itself despite having already played for Real Madrid in the past. The Argentina international was at the Santiago Bernabeu from 2010 to 2014 and won the 2013-14 Champions League in his final season. Speaking with So Foot ahead of the first leg of PSG's Champions League round-of-16 tie with Madrid, Di Maria admitted that the idea of playing for their rivals does not pose a problem. The 30-year-old added that the only club he will not sign for is formative club Rosario Central's bitter rivals Newell's Old Boys. "My relationship with Real is over," Di Maria said. "I completed my cycle there a long time ago. "Honestly, I would have no problem playing for Barca -- the contrary, in fact. The only club that I will never sign for is Newell's because I am a Central fan."
