Salomon Kalou admits Chelsea cannot afford to drop any points if they're to pip Manchester United for the Premiership title.
Kalou, who scored in the 2-0 win at Man City on Saturday, reckons they cannot drop points before the Stamford Bridge meeting.
He said: "There are still games to go and there is always hope.
"We still have to play Manchester United at home, so we still believe in the title.
"But in the end we have to win every game before we meet United."
