His goal against West Ham was his first from open play in 11 months and Lukaku says he needs to get back to scoring regularly if he is to win his England spot back.
He told the Echo: “At the minute, the players who play in his position – like Dele Alli and Wayne Rooney – they have got goals in them. I think Ross has to get more goals and more assists than he has been doing. If he does that, then he is going to play.
“If Ross fulfils his potential, you are talking about the best player in English football. He has got everything.
“He has got power, he has got technique; he can shoot with both feet. He is fast, he can pick a pass. The manager has been working with him so he makes the right decisions on the pitch.”
