Romelu Lukaku has not been his former self recently and has now shed light on what is holding him back.

Romelu Lukaku was Manchester United’s top goalscorer last season with 27 goals in all competitions but only has two goals since mid-September in this campaign. The forward admitted that he bulked for his World Cup participation with Belgium, saying it was a good fit internationally but not for the Premier League, reported the Guardian.

“In the Premier League, I cannot play with the same amount of muscle as international football,” he said. “That was something that when I came back I knew straight away: ‘Nah, I cannot play in this style like this.’ I had to lose muscle, basically. So you just stay out of the gym, drink a lot of water, and a lot of veg and fish, and it helps.”

Lukaku also stated that he has been tired since the World Cup ended, hindering his ability to play aggressively.

“After the World Cup, I think I really was a bit tired,” he said. “But, you know, I had the same thing in 2014 after the World Cup when I came back to Everton, I was really in a slump after the World Cup. So now I think I am at a decent level again and ready to go again. I knew this. Me and the [United] medical staff, we did like a lot of tests to see what was the problem. I had a hamstring injury, which is something that never happens to me.”

Romelu Lukaku has six goals in 20 games for United this season and Jose Mourinho no longer trusts the star forward in his starting lineup. Manchester United is currently in sixth place, trailing Arsenal and Chelsea by eight points.
