Koeman has improved Lukaku's game

Cape Town - Everton defender Luke Garbutt says the arrival of manager Ronald Koeman has improved striker Romelu Lukaku this season.

Lukaku has started the new campaign in fine form, netting five goals in six games.

A notable change is the goals Lukaku has scored with his head - something which rarely occurred in previous campaigns.

Garbutt claims the towering striker was not particularly fond of ariel duels and didn't feel confident enough to try and get on the end of crosses, but their new Dutch head coach has worked on that specific weakness.

"At the time he wasn't particularly confident and I don't know if he was ducking out of the way of headers," he told the Liverpool Echo website.

"Because he's scored a header this season against Sunderland and has had a couple of good opportunities where he's stuck his head in there; I don't know whether Koeman has said to him he needs to do more in the air.

"He used to say to me that heading wasn't really his strong point."
