Rafael Benitez has refused to rule out a return to manage his old club Liverpool in the future.

The Spaniard will lead his current team Chelsea against Everton at Goodison Park in the Premier League on Sunday.

"At the moment, I'm really pleased here," Benitez told reporters. "I want to keep winning and you never know what can happen in football.

"I have a very good relationship with the fans and the city [of Liverpool] but I'm a good professional and that means I will give 100% for this club."

Benitez managed Liverpool from 2004 until 2010 and led them to Champions League triumph in 2005.
