Three goals in two Premier League games represents a pretty emphatic start to Romelu Lukaku's career at Manchester United.

His brace against West Ham showed exactly why Jose Mourinho spent £75 million on him this summer, demonstrating his pace, strength and finishing ability.

Then, in Saturday's 4-0 win over Swansea City, the Belgian confidently fired past Lukasz Fabianski when played through by Henrikh Mkhitaryan.

Lukaku is far from the finished product and at 24-years-old has time on his side to iron out the flaws in his game.

Football fans are highly critical of his touch, for example, while his decision making often leaves a lot to be desired.

United fans can hardly complain about the start he's made to life in Manchester, yet Thierry Henry still found reason to criticise following the Swansea victory.

Speaking on Sky Sports, the Arsenal legend claimed Lukaku's movement and link-up play still needs some work, despite two of his goals for United coming from making runs in behind.

"That's [movement] something he needs to bring to his game," said Henry. "We all know what he can do.

"If you want to take it to another level at Man Utd - four goals in three official games is remarkable - it is about getting better. He will work on it, he's with special players and he's with [Jose] Mourinho.

"Mourinho will help him to develop that side of the game. We all know he has the one thing that's most important, when you feed him in the box, he will score."

Lukaku may feel hard done by following Henry's comments. He's scored three goals in two games for United - what more can he do?

Alan Shearer has now jumped to the Belgian's defence by saying he's doing exactly what Mourinho signed him for and to ignore his critics, like Henry.

He wrote for The Sun: "On Saturday, there was some criticism about his (Lukaku's) movement in the link-up play, yet Mourinho said in the summer he was not interested in all that and he was not that type of player.

"He just wanted a goalscorer operating in and around the box to put the ball away. All this business about strikers dropping deep to link up play is overrated in my opinion anyway.

"In my time at Newcastle, if we were going through a bad spell I found myself dropping deeper to help my teammates.

"But at the same time, this was negating my greatest strength. When we were playing well and I was on the shoulder of the last defender, we were dangerous."

Well said, Alan. United spent £75 million on Lukaku to score goals and so far he's delivered three in two games, so what is there to complain about?
