My family were more nervous than me about Manchester United move - Anthony Martial

The 19-year-old, dubbed the new Thierry Henry despite making barely 50 first-team appearances for the Ligue 1 side, moved to Old Trafford for a reported 36 million pounds.

However, the forward told a news conference in France on Wednesday he was not concerned about the size of the fee.

"My family were definitely a bit nervous because of my high price but I'm going to stay focused on my work," he said.

"I don't worry about the sums. The price is between the two clubs and I'm going there for the football side.

"I don't see myself as being under any pressure. Since I was young, people have told me I have the right characteristics to play in England."

Martial said United manager Louis van Gaal had asked him his best position and been told it was in the centre.

"But he told me I can play in a number of positions," the French Under-21 international added. "It's the coach who decides."

Nor did Martial appear overawed by the prospect of featuring alongside players like England captain Wayne Rooney.

"It's normal Wayne Rooney doesn't know me," he said. "Next to him I'll improve my game a lot."

Former Arsenal hero Theirry Henry has labelled new Manchester United forward Anthony Martial a 'massive gamble'.

Despite him being dubbed "the next Henry" by some pundits, the real Henry is not convinced about the youngster's prospects.

"He [Martial] has pace, can he score a lot of goals?" he said. "I actually don't know because he's only played 52 games. It's a weird one for me to say. It's a massive gamble that you need to take nowadays because of the situation Man United have."

"We saw him at the Emirates last season playing with Monaco and causing trouble to the Arsenal defence, he has a bright future," he added. "But there's always a question mark, whether he can perform.

"[Martial] played at the weekend against Paris Saint-Germain and he can play in the middle. Is it going to take him a bit of time to adjust and understand what the job requires? Yes, because he only played 52 professional games. It [the fee] is mind-blowing."
