The Spanish tactician has come to England with an enormous amount of fanfare following successful stints with Spanish giants Barcelona, where he worked alongside Valdes, and German powerhouse Bayern Munich.
34-year-old Valdes learnt plenty from his time at Camp Nou with Pep and is keen to see how the great manager gets on in the Premier League.
Valdes told Sky Sports News HQ: "It will be interesting to see Pep's style and philosophy in the Premier League.
"I'm happy for him because he has always wanted to manage in England but could find it difficult to adapt.
"I remember Pep always saying 'Casa, Casa', which translates to 'go home'. He thinks the centre of the pitch is home, and he wanted the players to return the ball there as soon as possible.
"It's more for the players than the goalkeeper but he wants a keeper who gives the defenders an option. But the most important thing for him is a keeper who makes saves!
"Our philosophy in the Barca academy is always the same. We are shown as kids to play their way, and the goalkeepers have to learn to play like outfield players."
