LOUIS VAN GAAL was quick to ingratiate himself with the Old Trafford faithful yesterday, calling Manchester United the “biggest club of the world” in his first appearance as boss.

The former Bayern Munich, Ajax and Barcelona manager, who was announced as David Moyes’s successor in May, took his first training session yesterday morning before addressing the size of the challenge ahead of him at United.

“I will do my best and that’s what I can give. I cannot give predictions because you never know. It’s the biggest club of the world, which I know already after two days,” the 62-year-old, who has won league titles with every club he has managed, told a press conference.

“I have to adapt to this club. It shall not be easy, but I will do my utmost best. When you see my career, you can see what I have won and that is what I can say. The future shall show if I can do that again.”

Van Gaal’s work with Holland at the World Cup — guiding them to third place — delayed his introduction at Old Trafford.

He arrived at the club’s Carrington training ground for a low-key first day on Wednesday before being unveiled to the press yesterday.

He said he couldn’t take a holiday after the World Cup with such a big challenge hanging over him.

“I could not let them go. When you are asked by the biggest club in the world, it’s a big chance for me,” he said.

“When there is a challenge like this, I never let it go.”
