The Argentinian only completed his £59.7million transfer from Real Madrid on Tuesday, but has been deemed fit enough to take his bow at Turf Moor.
“He has impressed me,” the boss told MUTV’s Stewart Gardner on Friday. “The first training session was with all the boys and he was very impressive. The second was a little bit less so but he has to adapt to the culture and the players with whom he shall play.
“It is the other way around also: the Man United players have to adapt to his way of playing. I believe he is ready to play. He is fit enough. He played a match in Madrid and he is ready to play.”
Asked if Turf Moor will provide a culture shock for Di Maria, a former resident of the Bernabeu, van Gaal said: “A game is a game and a match is a match. He has a lot of hunger to play because he wants to support Manchester United. He said it in the press conference. He is a very modest guy. He wants to work for the team so I am very curious about his first appearance.”
Van Gaal has repeatedly stressed it will take around three months for the players to adapt to his philosophy and the new 3-5-2 formation. Nevertheless, he is continually looking for improvement and hopes his side can up their game on Saturday.
