Porto coach Julen Lopetegui heaped praise on goalkeeper Iker Casillas, who has settled in seamlessly in Portugal.
Casillas ended his 25-year association with Real by signing a two-year contract with Porto last month and the Spain international has hit the ground running, helping the Portuguese giants to a 5-4 penalty shoot-out win over Valencia in a friendly on Saturday.
Speaking afterwards, Lopetegui said: "He is a player that comes with experience. He has arrived at the club with the enthusiasm of a 20-year-old lad.
"He has come to a big club and we are all going to benefit from his enthusiasm."
"I am very grateful to the fans. Now I will try and repay that love with more good performances and victories for Porto," Casillas added.
"The team was fine defensively, we had a lot of the ball and we’re happy. It's good to win in the pre-season and pick up a winning mentality."
