West Ham boss Gianfranco Zola is pleased to see good friend Ray Wilkins back at Chelsea.
Wilkins joins Chelsea as a direct replacement for Steve Clarke, who moved to West Ham this week to become Zola's No2.
He said: "I am sure he will do well. He has the knowledge to do the job and knows the Premier League very well.
"And he is a very humble man so I am sure he will be very helpful for Scolari.
"He knows the club and the supporters. He can do a great job and he is a very good man. I worked with him for a few years and it was always a pleasure."
