Football agent Jorge Mendes believes that Manchester United will never find a manager who is of the same calibre as Sir Alex Ferguson.

Louis van Gaal currently occupies the Old Trafford hotseat, but Mendes believes that Jose Mourinho is the only other "genius" manager in the Premier League.

"[United chief executive Ed Woodward] is the right guy to drive Manchester United to find a way to win important trophies," Mendes told BBC Sport.

"But at the same time, he has just one problem - it's completely impossible to find someone like Sir Alex Ferguson because he's a god, he's a genius and to find a genius is very difficult.

"You have one in England - Jose Mourinho. Having Sir Alex Ferguson ensures at this moment you have 12 or 15 points more. He's finished his career, but he's someone that's the difference."

Mendes represents numerous footballers, including Cristiano Ronaldo and David de Gea.
