Kepa Arrizabalaga has claimed Chelsea must win against Tottenham to restablish their form in front of a home crowd.
The Blues have played three consecutive away matches in the last week, recording a win, loss and a draw, with the victory coming against Tottenham in the Carabao Cup.
However, the club's Premier League form has been more sketchy with Thomas Tuchel's men without a win since Boxing Day, against Aston Villa.
