Everton manager Roberto Martinez is confident that Romelu Lukaku can become one of the world's best strikers.

The Belgium international had an inconsistent start to the season in front of goal, but in 2015, the forward has netted 11 times in 16 games.

A hamstring injury forced Lukaku out of two matches, but he made a substitute appearance in last weekend's 1-0 win over Burnley at Goodison Park.

"Rom has a very critical view of himself, but I think that'll help him become one of the best strikers in world football," Martinez said in this morning's press conference.

Lukaku signed for Everton for £28m from Chelsea last summer following an impressive loan spell on Merseyside.
