Giovani Dos Santos cannot wait for his first London derby on Sunday, but he has issued a word of warning on one Chelsea player he will be very familiar with.
The 19-year-old was a team-mate of Deco - a man who has hit two goals in his first two games for the Blues - at Barcelona last season.
Gio has no hesitation in saying the Portuguese international is one of the world's best midfielders, but is also confident we can get a result at Stamford Bridge.
He said: "Deco is a very good player. I know him well and I think he's one of the best in the world in his position.
"It's no surprise for me that he's come to England and has made an instant impression on Chelsea.
"They are a very strong side with good players. But if we play with confidence and work hard for each other, we can get a result.
"It's a big game for the Club and a special one for me because it's my first London derby, so I'm hoping we can get a good result.
"It will be a new experience for me and the fans will be very passionate, so we need to repay them with a good performance."
