Manchester United midfielder Memphis Depay has admitted that he has failed to justify Louis van Gaal's faith after the Dutch manager initially forked out around £25m ($35m) with the club set to pay a further £6m in add-ons to sign him from PSV Eindhoven last summer. The Netherlands international turned down a move to Paris Saint-Germain to play under his former national team manager.

The 22-year-old attacker was touted as one of the best young prospects in Europe following his heroics during the 2014 World Cup, where he was named the young player of the tournament, as well as scoring 22 goals in 30 appearances to lead PSV to the Eredivisie title last season. This prompted the former Bayern Munich and Barcelona manager to personally ensure that he chose United over other interested clubs.

Depay, however, has flattered to deceive and since the start of the season has managed just two goals in 20 Premier League appearances. He has also lost his place in the starting XI with Anthony Martial and Jesse Lingard preferred in the wide roles. The Dutchman also came under criticism for his lacklustre performances in recent months, which has seen him being held responsible for mistakes that led to goals during their loss to Stoke City and the last gasp draw against Chelsea.

The former PSV star has vowed to work hard and fulfill his potential at the club and believes assistant manager Ryan Giggs, who has in the past criticised him for his lack of dedication, will assist him in improving and adapting to the Premier League.

"No, not yet [on meeting expectations]. I will continue to fight for it though. I have a lot of expectations of myself and I am busy trying to improve. You learn from mistakes and those [good] moments will come," Depay said, as quoted by The Times.

"Ryan Giggs is a legend, he talks a lot with me, he gives me advice, he has experienced everything already so he can help me with lots of things. He works a lot with me and he and Wayne Rooney give me lots to think about. That really inspires me because they are legends, I feel that I am doing something well with them," he added.
