Habib Beye: "I know the atmosphere of a Paris Saint Germain-Marseilles game but I haven't yet experienced the full atmosphere of a Newcastle-Sunderland match. I will find out what it is like on Sunday.
"Sunderland is a good team but we are confident. We want to win the last four games. It's very important for next season. In the first game (between the sides this season) I came on for the last half an hour.
"It was a big atmosphere because Sunderland really wanted to beat Newcastle. Now it's different because we're playing at home and with 50,000 fans behind us.
"But when you've played in a Marseilles v Paris Saint Germain game it's more intense. Marseilles hate Paris Saint Germain and vice versa. In England you don't have a problem with hooligans any more. In France you still have some.
"The two clubs are very far apart, but 10 years ago Paris were a big, big club, and Marseilles as well. They would always have a big fight to win the league and the French Cup.
"I remember two years ago when PSG fans broke the windows of the Marseilles team bus when we played there. None of the players were hurt, although the driver was hit on his head by a rock. In England you can't do that. In France it's crazy."
"I've never played against Roy Keane but he was a very good player. When I was younger I watched big teams. Manchester United were a big team and Roy Keane was a big player. When Sunderland play you can see something of him in their style.
"I prefer the atmosphere at derby matches. I wouldn't say the football is a party, but it's a game. You can't have fights between fans of Newcastle and Sunderland at the stadium, it's just football.
"I realise the fans hate each other. I bought a new house near Ponteland recently and the two men working on it, one was a Newcastle fan, the other supported Sunderland. The Newcastle fan was telling me, 'Don't lose because on Sunday I hate this guy! The rest of the time I love him but on Sunday I hate him!'
"It's good. You always want to win against Sunderland, against all the teams, but it's just a game. You can't have people fighting about football. When you see people in the streets they always tell you we need to win.
"It's a good atmosphere for a player because you have a little pressure. There's a bit on you when you play teams like Portsmouth but, before a game like this, everybody talks about it. You can maybe lose a game during the season but not this one."
