He said: "I've played against Brett a lot of times, not only when he was at AZ but when he was younger he played at Feyenoord.
"He's a great player and it's good for him, too, to come to a club like this and to make a step up.
"In Holland he showed his quality and now it's good to have him next to me. He's a great player to play with and he never gives up. I don't think I ever saw him standing still on the pitch."
