Manchester United midfielder Juan Mata has described the falling out between Red Devils boss Louis van Gaal and goalkeeper Victor Valdes as a 'shame'.

The former Barcelona shot-stopper has only made two first team appearances for United since joining the club last summer.

The 33-year-old has found himself frozen out of the United dressing room, a situation which Mata describes as disappointing.

"It is a shame what has happened with him as he is a great goalkeeper," Mata told Onda Cero.

"He wants to compete and has proved himself as a goalkeeper. I don't know what happened between him and Van Gaal, that is something only they can say."
