What's the fiercest derby you've played in? Ahead of Derby Day on Sky Sports, we asked the Soccer Saturday pundits for their verdicts...

Paul Merson - Arsenal v Tottenham I never used to get involved in all that stuff, it was not my job to tackle, I was paid to make things happen on the pitch!

But I would have to say both FA semi-finals at Wembley in 1991 and 1993. Losing in the FA Cup semi-final was the ultimate game to lose in those days as the FA Cup was huge, it was the biggest thing. To lose in that to Tottenham was the ultimate.
