Manchester United manager Louis van Gaal has warned Memphis Depay he will have to adapt to the Premier League soon if he is to remain at Old Trafford, or end up like Radamel Falcao and Angel Di Maria.

Both Falcao and Di Maria only lasted one season at United, having both never truly adapted to England's top flight. Di Maria was sold to Paris Saint-Germain this summer, while Falcao's loan from Monaco ended and United decided against making his move permanent.

Van Gaal said that Depay, who was an unused subsitute in United's 3-0 win over Everton at the weekend, has "a lot of quality" but is not yet fitting in with the team's "philosophy".

“Some players cannot adapt to the team philosophy,” Van Gaal told reporters after the win. “That you cannot know in advance. You have to see that.

“Because you see a lot of qualities in a player, but Depay has to put that quality in service of your team.

“That also happened with Di María and Falcao – both great players but you have to fit in with the philosophy. Not only with Memphis, with every player that we have bought."

Van Gaal added: "Do I still believe in him? Of course.

“The problem with young players is they are not consistent. That you have to learn. We have to give him time.”

United are third in the table, two points behind Manchester City, who they play next weekend. Van Gaal said he was happy with the way his team responded against Everton aftert losing to Arsenal in their last match.

"I am very happy with the response of my players and I am very proud of the performance. I think it was an excellent performance and maybe it is the start of many, many victories."

"I am a very happy coach because I have seen a lot of good individual players in my team. That also gives confidence for the matches against CSKA Moscow [in the Champions League] and Manchester City," said Van Gaal.

Further good news for United was the return of utility player Phil Jones for his first game of the season after recovering from a mild case of thrombosis.

Marcos Rojo and Herrera also impressed, as did Schneiderlin, as Van Gaal juggled his squad ahead of a big week which begins in Moscow on Wednesday.

"They played very well, I have to say that," Van Gaal said.

"[Rojo] had not played 90 minutes for me this season, it was his first 90 minutes, and also for Phil Jones. These changes were also question marks before the game, I didn't know if they could play for 90 minutes."

Rooney's goal was his first away from home in the Premier League for 11 months and answered some of his critics.

"I said a lot in a press conference last Friday, we have to score like a team," Van Gaal said. "Because of the attention on Wayne I am happy he scored, I believe his last goal here was in 2007. That is crazy but now I think he shall score more."
