Chelsea midfielder Joe Cole admits he is happy to see Patrick Vieira back in England at Manchester City.

Cole loved locking horns with Vieira when the Frenchman was captain of Arsenal.

"When I was playing in midfield at West Ham I used to love playing against Roy Keane and Patrick Vieira. They were the two best players in their position in the world at the time and I used to really enjoy the challenge as an 18, 19, 20-year-old," Cole told Chelsea TV.

"I still take a lot of pleasure from some of the games I played against them. I did occasionally get the upper hand but it was only occasionally because they were great players. It was a great challenge and I do love a challenge."
