Manchester United boss Louis van Gaal is hesitating over their move for Porto defender Eliaquim Mangala.
Sources from the Frenchman's camp have made it clear that Mangala favours a move to United over rivals Manchester City and Chelsea.
However, Van Gaal has his doubts about the player's temperament and whether he can lead United's new-look back four next season.
Meanwhile, tribalfootball.com understands one unnamed Premier League manager rates Mangala "as the most complete defender in Europe".
