Thierry Henry thinks Manchester United should sack Louis van Gaal and replace him with José Mourinho. The 38-year-old Frenchman is a long-time admirer of the Dutch coach, but has claimed his methods are not working at Old Trafford.

Henry explained that Van Gaal has failed to deliver eye-catching football since becoming United's manager in 2014. The former Arsenal striker thinks the United hierarchy would be better served putting their faith in Mourinho.

"I know a lot of United fans and all they talk about is how poorly their team are playing," Henry wrote in The Sun on Sunday. "It's not about results any more. Even when they win, the issue is still how awful the football is. They don't enjoy watching their team any more. They are bored.

"No one can question Van Gaal's pedigree as a coach. But he has failed to get his message across at United and the players don't know what is expected of them. He doesn't appear to know his best team or even his best formation."

Henry claimed Mourinho is the obvious answer to United's current woes. The Portuguese has been linked to the managerial role at Old Trafford for a number of years and Henry thinks he is guaranteed to win trophies at United.

"The club are crying out for success and Mourinho guarantees that, in spite of everything that happened at Chelsea this season. He is still an amazing coach and United have got to do something because it is simply not working [for Van Gaal]," he said.

United currently sit in fifth position in the Premier League, following a woeful run of results through December. However, Van Gaal recently denied speculation he had offered his resignation to the Old Trafford board.
