If Arsenal win the derby on Sunday the celebrations will stretch from the red half of north London to a Red Bull in Tucson.

That's where Thierry Henry will be watching after returning to the United States last week to prepare for the new MLS season with his New York team-mates.

The 34-year-old will be resting after a Desert Diamond Cup clash with the New England Revolution when Sunday's local affair kicks off in London, but this is one game the former Arsenal player - and full-time Arsenal fan - will not want to miss.

And Henry believes three points against Spurs could kick-start his old club's campaign.

"I will be in Arizona for a pre-season camp and for sure I won't be watching it with [New York team-mate] Teemu Tainio because he's a Tottenham fan!" Henry told Arsenal Player.

"For years we have been used to being on top of Tottenham, by a mile, and now it is the opposite. But this is the derby, which you don't want to lose, and we need those three points massively.

"Hopefully it will be the derby that can spark the players, the fans, everybody at Arsenal Football Club. We'll see.

"The league is going to be very difficult but the top four is in Arsenal's hands. They have the squad, there is a long way to go, they have to play Chelsea at home, Tottenham at home, Newcastle at home, Man City at home… it is not impossible."

Thierry gave a special farewell interview to Arsenal Player following the final appearance of his loan spell against AC Milan. Both parts of this interview are available now.
