Belgium coach Roberto Martinez has sung the praises of Inter Milan striker Romelu Lukaku.

Martinez says former Inter coach Antonio Conte has been key to Lukaku's improvement.

"We're talking about a Romelu Lukaku that is more than a goalscorer since he moved to Inter. He arrived at the right club, at the right time, with the right coach [Antonio Conte] and has developed this incredible maturity," said Martinez.

“That is not just the goalscorer that we all know," he continued, “He is someone that can affect the game, he can affect players around him. He can really really influence what you're going to do on the pitch."

“He is still 28, the goalscoring records are amazing, but I think Romelu Lukaku has become a very mature footballer in the last 14 months."
