Former Tottenham midfielder Jamie O'Hara says Arsenal are the biggest club in London.
Chelsea were crowned European champions for the second time on Saturday, beating Premier League champions Manchester City in Porto.
It was the 17th major trophy Chelsea have won since Roman Abramovich started bankrolling their success in 2003; including five league titles to the Gunners' one.
But O'Hara said on talkSPORT: "I'm a Spurs fan, but you can't get away from the fact Arsenal are the biggest club in London. If you're going on history, real success over a football club, fanbase and everything that comes with a football club.
"Chelsea are the most successful club in London right now, we know that, they.ve got a billionaire owner and they are the most successful club."
He added: "You can class it as a stupid argument because they're both huge football clubs, but at the end of the day if you're asking who is bigger, who is the biggest club in London, it's Arsenal! They've won the most trophies, they've been the most successful club."
