Juan Mata has no desire to speak about the possibility of Jose Mourinho returning to Chelsea while Rafael Benitez remains in charge at Stamford Bridge.
Mourinho guided Chelsea to back-to-back Premier League titles, the FA Cup, two League Cups and the FA Community Shield during his three years in charge but he left after falling out with owner Roman Abramovich.
The Portuguese manager remains hugely popular with Blues fans and they would love nothing more than for him to return to the club in the summer.
Currently the coach at Real Madrid, Mourinho’s future at the Bernabeu is uncertain following a disappointing domestic campaign and he has been linked with a return to Stamford Bridge.
While Benitez is expected to leave when his contract expires, Mata is unwilling to discuss who should take over from the Spaniard.
"Chelsea have fond memories of Mourinho. Things went well under him, he won titles and the fans will have a great memory [of him], but today, Mourinho is the coach of Real Madrid and Benitez is Chelsea's coach. We have to be focused on that," he told Movistar.
"Of course, Mourinho is one of the best coaches out there, but I do not know what will happen [with his future]. For now, I'm enjoying Benitez and his way of training."
Should Mourinho leave Real Madrid, the Chelsea midfielder believes former Blues manager Andre Villas-Boas would be the perfect candidate to take over at the Bernabeu.
"I think Villas Boas is a great coach, modern, young, and with experience and qualifications, although his time at Chelsea did not go well at all," he added.
“Myself and him have a great relationship and I will always be grateful. He's ready to coach any team."
