The Spaniard, was speaking after he watched the team defeat Middlesbrough 2-0 in the FA Cup fifth round, to book a place against Manchester United in the quarter-finals.
He said: “Chelsea gave me the title of interim manager which is a massive mistake. I’m the manager.
“The fans are not helping us. At the end of the season I will leave. They don’t have to worry about me.”
He went ahead to take a dig at the fans, who constantly boo and sing against him at games.
“I am a little bit disappointed with some of the fans. They have to support the team instead of wasting time singing songs,” he continued. “If they continue singing and talking, they are not doing [the team] any favours. I will do my best until the last day.
