West Bromwich Albion goalkeeper Ben Foster regards Romelu Lukaku as a potential worldbeater.

Lukaku is on-loan at West Brom from Chelsea.

Foster said: "We call him Big Rom or Big 'Un.

"He's a tank. He is such a huge talent, at £18m, you have to have something for that kind of money and he is showing that now.

"He's only 19, it's frightening. He could go on to be an absolute world-beater."
