Tottenham vs Chelsea is a rivalry of epic proportions and one man who has played for both didn't pull any punches about where his allegiances lie.
talkSPORT host Jason Cundy played for both during his Premier League career - but his colours are firmly nailed to the mast.

And that's despite being forced to sign for Spurs while being a lifelong Blues supporter.
Ahead of the huge London derby, Cundy was ribbed about his Tottenham past on talkSPORT's YouTube show Inside Chelsea.
"Well, it was terrible," he laughed.
"I mean, I don't even want to talk, move on please. I can't talk about it.

"I've got no love for Spurs at all," he continued. "I dislike Spurs as much now as I did before I joined them."
Cundy was part of Chelsea's academy but left Stamford Bridge in 1992 after 41 league appearances and two goals.
He joined Tottenham on loan initial but then left permanently for White Hart Lane in the same year.
The defender spent four years on the books with the north London club but only managed 18 league appearances, before leaving for Ipswich in 1996.
Asked how challenging the transfer was for him, he added: "It was a very odd scenario because I just signed a four and a half year contract in the November, and by the time March came around, Chelsea accepted a bid.
"I had a phone call from Ian Porterfield saying to me, 'We've accepted a bid and Terry Venables is going to phone you this afternoon'.

"It was very different back then because, if the club wanted you gone, you went.
"And now the players got far more power. If the club want you out, they want you out. And they wanted the money more than me. Chelsea made their choices.
"They made their decisions. And unfortunately, I had no choice but to make mine. But look, it's part of my life. It happened.
"And, you know, I'm very lucky now. I went away, but I've come back."
The clash between the two sides is set to be fiery coming just over one year after Chelsea beat nine-man Tottenham 4-1.
The game saw Cristian Romero and Destiny Udogie sent off, while James Maddison and Micky van der Ven were forced off through injury.

Battles between the two sides have historically been explosive too.
And asked if that fire was always there, he added: "Even the youth team. It was ingrained in you in the youth team what this game meant.
"But as a Chelsea fan, I didn't need to be told because it was very much there that. The game will crackle.
And there's certain games, and this is why I love football, because there's certain games at certain stadiums where you know you're at something big.

"I know that Brentford are a west London rival. Brentford under the lights or Spurs under the lights. Let me tell you, you can't compare the two.
"There is nothing compared. And whoever's going to be at the stadium at the weekend, Chelsea fans, right? They'll be in. That will be like a proper, proper battle."
