"We have three important games in the next week. They are all difficult - Everton away, Besiktas away and then Arsenal home," said the Spaniard.
"We need to win all three games and for us that is important. Maybe we need to improve performances, but we also need to win those games.
"We still think the Premier League title is possible. We have a chance, but we need to fight for the title.
"We are still unbeaten in the Premier League and we need to keep working and train really hard," he added. "We have confidence and Arsenal are only six points ahead of us. That is not too much.
"If we beat them it is just three points."
