Romelu Lukaku waiting for things to 'click' at Manchester United

MANCHESTER, England -- Romelu Lukaku said he is still waiting for things to click at Manchester United.

The striker, into his second season at Old Trafford following a £75 million move from Everton in 2016, is on a run of seven games without a goal for his club.

Lukaku has scored four goals in 12 games this season -- a contrast to last season when he netted 11 times over the same period.

Another blank against Juventus on Tuesday would make it the 25-year-old's longest barren run for United but he insists he is not worried.

"With Belgium I've been playing for 10 years since I was 16," he told a news conference on Monday.

"Players know me much more. Here I still think my teamwork between myself and my teammates can improve and be much better.

"It's something that we're working on. The players need to know me and know my movement. When that starts clicking I think the results I have with Belgium will also come here."

United face Juventus at Old Trafford on Tuesday night on the back of two positive results against Newcastle and Chelsea.

In both games they had to battle back after going in at half-time behind and Lukaku has urged his teammates to start on the front foot against the Italian champions.

"In the first halves we started slowly," he said. "No initiative on the ball, no movement. In the second halves, everything that we said we wanted to do in the first half we did.

"That's why we came back and got great results. Now the key is to start games like we do in the second half.

"The mood is really positive. Obviously we're disappointed with how the game ended against Chelsea.

"It's going to take time to be where we want to be but the last two games have shown that we can play, we can press forward and we have played to make a difference.

"The work that we're doing behind the scenes has to be delivered into wins."

United are second in Group H with four points from two games, behind Juve who have a 100 percent record.
