Park Ji-sung has been recalling his first days at Manchester United.

The South Korean joined United from PSV Eindhoven.

"When I joined the first training session I looked around and saw all the players I used to watch on TV," Park told

"I was like, 'Can I play with these players?' It was weird. I was confident in my ability, but it was just strange to be alongside these players. There were moments in training, like making a good pass or scoring a goal, that built my confidence.

"After I signed, even before I signed - when I did the medical test - I had a look around and it was clear this was the biggest club in the world. I remember it being a really proud moment."
