Chelsea midfielder Juan Mata is tightlipped on talk of Real Madrid coach Jose Mourinho returning to the club.

The Portuguese boss is being touted as a potential successor to interim manager Rafael Benitez in the summer.

Mata said: "They (Chelsea) keep fond memories of Mourinho. They did very well, won titles and the fans will keep a great memory.

"But today Mourinho is the coach of Real Madrid and Benitez of Chelsea. We have to be focused on that."
