Arsenal legend Thierry Henry has praised Romelu Lukaku for his performance in Manchester United's 4-0 win over West Ham United on Sunday.

However, the Sky Sports pundit did criticise the Belgian for his inability to retain possession effectively.

Lukaku scored a brace on his debut for the Red Devils, but according to Henry, he gave the ball away a startling 18 times.

"He was close to a hat-trick, he scored goals we expected him to score, and there are bits he can work on," Henry told Sky Sports. "But what a start to his Manchester United career.

"The possession, this is the thing for me he needs to work on. He lost it 18 times and that is a tiny bit too much.

"Other than that he had an amazing start. He could have had a hat-trick but he did what he is supposed to do."
