Former Atletico Madrid defender Filipe Luis hails Chelsea for making Stamford Bridge a fortress this season.
Mourinho's side are unbeaten at home and their 2-0 win over Newcastle made it their 10th home win of the campaign, thanks to goals by Oscar and Diego Costa.
And Felipe had nothing but praise for the team as they maintained their 100 per cent home win record this season.
“It is very difficult to play against Chelsea at Stamford Bridge and we feel really comfortable, we know how to play on our pitch,” said Luis as The Sport Review reported.
“The team is doing great and we have to keep going and fighting to the end because everybody wants to beat us here. The Premier League is a difficult competition. We have to keep working.
“When you are in front is the always easier but especially in the Premier League you can never sleep in the game because if you do, in one minute the opposition can score,” Luis added.
“The team defended well in the second half [against Newcastle] with a lot of concentration and in attack we have lethal players and they can improvise a lot so it is really difficult to stop them.”
