Inter Milan player Lukaku talked about the doubts he faced in an interview with The Times. He said: "I am not slow at all. Now I don't care about those doubts."
Lukaku said in an interview: "A year ago, when I was in England, I was'lazy, not running, this player who does not do well, that player who does not do well."
"Now, people call me the hardest person in the locker room. If you look at me now and before, I did improve a bit, but it's still Lukaku."
"If you look at me now, you will see different results, a complete person, and a complete potential. See what I could have done in England."
"They will say I'm slow, and then I think,'Slow? I'm slow? I can't keep up with Manchester United's fast-paced games?'"
"I thought too much at the time and it was not right. If I were slow, I would not score like that in the Europa League semi-final against Shakhtar Donetsk."
"If I'm slow, I won't get a penalty against Sevilla. This is me two years later."
"Would you say that I was faster when I was 27 than when I was 25? This is exactly what I want to say. These are small things, you know what I mean, I don't care about them now."
