Chelsea defender David Luiz refuses to give up on winning the Premier League title.
Chelsea go to Swansea City on Sunday.
"It's still possible to win the league, so come on, let's enjoy the position we are in and believe, like we did against Paris St Germain," Luiz said on chelseafc.com.
"We need to have faith because we can still do it.
"Mathematically it's still possible but every game in the Premier League is difficult, as it will be on Sunday.
"Swansea are tough opponents and we've seen in the last few seasons, every time we go there it's a difficult game.
"We need to try to do our best and win the match."
