The 34 year-old World Cup winner told his club's website: "He is unbelievable. All the time I have pushed him, I tell him, listen Shaun, you have a lot of qualities. You need not all the time to stay on the line. You need to come back off the line and in midfield, nobody can catch you. And he listened very well and knows your moves.
"He has the possibility to score and make goals. I am happy for him."
