Manchester United new signing Anthony Martial will be ready to make his debut after the upcoming international break against Liverpool after completing his move to Old Trafford on deadline day. He could make his Premier League bow against his new side's bitterest rivals and the Frenchman has sent a stark warning to his imminent opponents.

BBC Sport understands the France youth international has moved to the 20-time English league champions for a fee that will eventually rise to £58m, making the 19-year-old the most expensive teenager in world football. Martial will wear the number nine shirt and is one of seven signings made by the club in the summer.

He could make his international debut in the friendly double-header against Portugal and Serbia prior to the resumption of the club season, which will see him return to United seeking his first start for his new team. Liverpool make the short journey down the M62 in the first game back and Martial says he will be ready should be handed his first appearance.

"I don't feel the pressure," he told MUTV. "I know there is pressure but I'm ready for it. I'm very happy because it's a big club in England. I'm very proud. I'm very happy because I worked hard for this and my family is very happy about it.

"I spoke with the coach, Louis van Gaal, and I know that I need to work very hard. It's not easy to speak about myself but I am a very fast player. I hope that everything will go well for me at this club. I'm very happy because the supporters are great here. I will be ready when the time comes."

Recent signings made by United manager Louis van Gaal have failed to adapt to the rigours of English football, with Angel di Maria leaving after a single season, while Radamel Falcao's loan move was not renewed beyond one campaign. The Dutch coach has heeded caution over expectations of the new recruit, admitting he needs time to acclimatise.

"I am so excited to be joining Manchester United," Martial told the club's official website. "I have enjoyed my time at AS Monaco and I would like to thank them and the fans for everything they have done for me. I have always wanted to play in the Premier League and to join the biggest club in the world is what every young footballer dreams of. I am looking forward to meeting my new teammates and working with Louis van Gaal who has achieved so much in his career."
