In the last 6 matches, Romel can not distinguish himself, but Juan Mata is confident that the forward will continue to score a lot.
"Romel has a strong character. He has been at the highest level since very young years, I know this, because I played with him in Chelsea, "Mata quotes The Mirror.
"I'm sure that goals will come - it's just a matter of time. Lukaku is a fantastic striker who has always demonstrated his talents. His ability to score was noticeable back in Chelsea ".
"This year he proves that he is capable of much. He is still young and in the style of the game reminds me of Didier Drogba. I think he can become an equally great striker, since he has a great potential, "the Spaniard concluded..
Earlier Romel himself asked the fans to show patience and promised to add in the game.
