Romelu Lukaku certainly appears to be going through a bad spell at Manchester United right now - with rumours even circulating that he's about to be dropped.

The Belgian striker started the season with four goals in his first five games but he hasn't struck since, although he did manage two for Belgium in the Nations League two weeks ago.

September 15th's trip to Watford was the last time that he put the ball in the back of the net for United, leaving him on an eight-game goal drought.

Lukaku's performance against Juventus on Tuesday evening may have been the last straw for many, with one notable piece of play seeing him struggle to get the ball under control before leathering it across the pitch, straight to Juve's Juan Cuadrado.

His instincts and confidence both look like they're lacking right now - at least in United's colours - so you certainly wouldn't blame Jose Mourinho for deciding that someone else should get a chance up top.

Marcus Rashford would be the obvious choice to step up in Lukaku's absence, but Anthony Martial and Alexis Sanchez could both be options for the weekend's game with Everton.

Although according to United legend Gary Neville, there's only one choice for Mourinho: stick with Lukaku.

"He's got to keep playing," said Neville, speaking at the launch of former United player Ben Thorley's book. "I lost my confidence for the six months going into the European Championships [in 2000] but I kept on playing through that period and in the end I came out of it at the other side.

"You play them through those bits of bad form and continue to give them that belief because you know full well they're still contributing when they're not playing well.

"I think that unless a player like Lukaku is feeling so down that he feels as though a break will do him good, you do try and keep them playing.

"But the top players tend to play through those dips in form."

Lukaku scored 27 goals in his debut season at United and Neville firmly believes that's enough 'credit' to give him the benefit of the doubt through his struggles.

"You build up a bank of credit," he added. "If David De Gea makes a mistake, no one's going to start going crazy about it because we know full well that players make mistakes - it's when those mistakes become regular.

"When you build up a faith, with everyone thinking you're a great player, it takes a lot then to say that something is not quite right.

"Romelu Lukaku is nowhere near that. It's a dip, it's not a slump."

Neville certainly has a lot of faith in Lukaku - we'll soon see if Mourinho can say the same.
