The quality at Antonio Conte's disposal was highlighted on Sunday when substitutes Cesc Fabregas and Willian came off the bench to play a role in securing a 3-0 win over Everton.
"Everton won their last eight home games, they've been on a good run and they score a lot of goals so to keep a clean sheet, play well and win was good".
"I am so pleased. In some games you need a bit of class". This is very important for our confidence for the final part of the season.
"It was a great game and a great achievement, ' said the Belgian winger".
"It's important to win and also have great enthusiasm to reach your target".
"We have made a massive stride, there's no getting away from that", he said.
"He is showing us great commitment in this season. I find it odd that the referee can give the penalty from where he is positioned", said Middlesbrough caretaker manager Steve Agnew. It is a great win. I hope it will be Diego who decides Sunday's game because that means we win the game. Former Chelsea striker Romelu Lukaku will have a point to prove against his former club and the fact that he has not scored in all of his five matches against Chelsea could be a cause for concern for Koeman.
"We must celebrate in the right way, with my players, with the staff, with our fans", he added. For sure it will be a really tough game for us but at the end of the season, I think every game becomes tough for many different reasons.
The Premier League leaders stepped up the pace after a tight first half to end up in full control at Goodison Park.
Chelsea have no injuries or suspensions so Conte will be expected to field out a similar starting 11 as he has done for most of this season.
Everton manager Ronald Koeman said his team did not deserve a 3-0 scoreline after holding Chelsea for over an hour, but conceded that he had "maybe" seen the champions in the final 30 minutes. "Maybe next week, maybe not - but it will not take longer than 10 days".
"From where I was I didn't think that it was a penalty and I thought Sane went down very easily". We started well and were a bit unlucky we hit the post.
Despite not creating many clear-cut chances there was a sense of foreboding about a Chelsea goal in the second half and after Jagielka nearly gifted them one with a blind backpass which Stekelenburg only just managed to clear before being clattered by Costa, who was booked, it duly arrived with just over an hour gone.
"After that it makes it more hard to create really open chances and if they get a little bit more space they are a team who will kill the game". The third goal was high quality [showing] the offensive side of Chelsea.
