Chelsea and Manchester City are currently running Arsenal the closest in the Premier League and held the leaders to a 1-1 draw at the weekend, despite Caicedo's red card.
And midfielder Enzo Fernandez insists they should be seen as proper title contenders, telling GiveMeSport: “Of course we are [title contenders]. This season, there are many contenders: Liverpool, Manchester City, Manchester United. All the teams are battling towards the top.
“There are some very strong Premier League sides. Arsenal have also been doing really well for many years. And Liverpool are a great side. I’m not going to choose one because they’re all good.
“And we know the Champions League is very tough. We’ll try to reach the final, which is what we deserve as a club. We’ve been doing well, so we’re capable of being right up there.”
On the lure of moving to west London, he added: "When Chelsea came in for me, I had no doubts. I wanted to make the move up, in sporting terms, to the Premier League.
“I wanted to come to Chelsea at all costs and didn’t want to let the opportunity pass me by. Everyone knows that and thank God it worked out. I’m here now and I’m very happy."
