The Blues have not lost in the Premier League under Jose Mourinho during either of his two spells in charge at Stamford Bridge.
"We are aware that it will not be easy, but we'll go there to get the three points.
"But we feel confident, we're doing things well and we want to get as many points as possible because we still have options to win the title.
"Of course there is an added pressure now. There are not many games left and we can't really afford to make any mistakes.
"If you lose three points that you thought you could win, they are difficult to recover.
"Also the teams coming from behind are pushing a lot. Now you play against teams away or at home that, at the beginning of the season, were not too concerned about losing because there were many games left.
"However, now they are fighting for survival and it is difficult to win against them."
