Everton manager Roberto Martinez has praised the role that Romelu Lukaku played in the team's comeback win over West Bromwich Albion.

The Toffees made it four games unbeaten as they came from two goals down to win 3-2 at The Hawthorns on Monday evening, with striker Lukaku netting a brace.

Martinez has said that the Belgian international showed great responsibility as he led the line.

"He has an elite brain and you can see when he puts his mind to it he can achieve anything," the Spaniard told ESPN.

"I always said Rom has got that unique strength of being the man the team needs and in the second half it wasn't a coincidence he was the one who scored the goal straight after.

"When you score two goals and you get an assist it's impressive. When you look at the way West Brom defend they are very good in what they do. He had a real desire to get on the end of the crosses and it made a real difference."

Everton sit fifth in the table following the victory.
