A first-half goal from Raheem Sterling and a controversial penalty by Kai Havertz overturned a first-leg deficit on Tuesday and propelled Chelsea into the Champions League quarter-finals with a 2-1 aggregate win over Borussia Dortmund.

A second-half goal from Kai Havertz earned nervy Chelsea their first Premier League win of 2023 on Sunday with a 1-0 victory over lively Crystal Palace, easing the pressure on manager Graham Potter after a poor run of form.

Kai Havertz believes Chelsea's 2-0 victory over Bournemouth can spark a winning run in the Premier League after a faltering spell before the World Cup.
