Chelsea defender David Luiz insists they're in the title race.

Chelsea are fourth in the table ahead of their match against Leicester at Stamford Bridge on Saturday and go into the festive period looking to make it three league wins in a row.

"Everybody knows the Premier League is so difficult, we have to think step by step," the Brazil international told Sky Sports News.

"Of course the boss tries to give us the maths and to give us one direction to follow and we trying to get the points to be there and fighting for the title not just for the top four.

"It's not my first Premier League [season] so I know anything can happen."
