Chelsea forward Cole Palmer's 16-game goal drought is due to a mental issue rather than a tactical or technical one, manager Enzo Maresca has said.

Palmer has gone 16 games without scoring for the club, having started the campaign with 14 goals in 23 appearances.

Palmer last scored on January 14 in a 2-2 draw against Bournemouth having previously netted 14 times this season in the Premier League.
