Anthony Martial needs to use Manchester United team-mate Edinson Cavani as a role model to become a better player, according to Dimitar Berbatov.
After scoring 23 goals in 48 matches last season - his best ever tally at the club - the French striker has been off the boil this campaign, only scoring twice in all competitions.
Martial, now 24, missed a sitter in a 3-1 home defeat to Paris Saint-Germain on Wednesday which leaves their Champions League progression uncertain.
And former Red Devils striker Berbatov believes the out-of-form Martial should take a leaf out of Cavani's book to improve his overall game.
