Martinez says Conte has helped Lukaku realise his potential.
“He scores like few others," Martinez told La Gazzetta dello Sport. “Create and score, create and score, create and score…
“He arrived in Milan at the perfect moment. He became a complete player, obviously thanks to Conte.
“Today, at his age, there are no striker as strong as him."
Martinez explained the Belgium international 'always had the potential' to become a decisive player and said his achievements aren't a fluke.
“In the past, Romelu always had the potential to be able to do what he is demonstrating in Milan," he continued. “For me it's not a surprise.
“For the first time in history, a played scored in five consecutive derbies. It happened to Lukaku, it can't be a coincidence."
