When you're a player for one of Manchester clubs and you're winning the derby, there's no better feeling.
On the other side of that, when you lose at the derby, you're feeling very, very low. Even lower, if you've scored two goals in the derby, at home, as I did.
In February 2005, I was with Manchester City when we lost 2-0 home to United. The first goal was given to United as my own goal. Then he scored again and was given to Wayne Rooney but he got rid of me. I tried to stop it but it went in and I had the last touch. It was going in any way but justified the direction of the ball a bit.
So, although the goal committee itself gives Rooney to me, I will claim that – two OGs in a derby home to their competitors. That is a terrible, terrible feeling and those are highlights and depression like the one in Manchester.
My first Manchester stadium was a real eye opener. Nobody remembers that he drew 1-1, he was more famous as the game where Roy Keane was sent off on Alf-Inge Haaland (below).
I learned in the City early what was meant by Manchester Derby. It's not just 90 minutes, this is all the construction work in the week. You know the games in advance, you know that the game is on the road, try to put it out of your head but before you know that the game is on you and you have to go out and play.
You're looking forward to but at the same time you're scared and this is the same game that everyone looks forward to.
When I started at City, United was the leading team in England, not just in the derby, and the City was only a middle-board team.
We were always in the armies and we were not expected to get a lot of it, but we seemed very reasonably at the derby.
I felt United of our opinion that we were not, that we would beat us irrespective of, even if it were not, so it was nice to have one over them. I think the games are higher for us because we want to have one over them because they win alliances and we were not.
The managers will aim to aim for the players so that they keep their focus but they live in the city, so no matter where they will go into the week of the derby people for talking to them about the game, let them know how important it is.
Here's the one. Here's the game where fans expect at least the effort from the players.
You can not always get an outcome but you have to put it at work. The city will have prepared so well for each game but it's the derby where the fans want to see that extra effort. Here are the supporters who have to deal with the results if they are losing. Supporters enter the work happy when they win and they are stunning when working when they are losing.
I had a few good battles in the derby over the years, but some games stood out. As in the 2002/03 season when we got to the United at home. This was our last season at Maine Road, so we know that we had to win one game for the fans.
Did we do, we won 3-1. That City's team was not as good as United: that was the side of Unified Giggs, Ferdinand, Scholes, van Nistelrooy and more, but the name comes out in an derby.
Shaun Goater scored twice for us. That showed how sometimes the derby throws an unlikely hero. Players can make their own legends in an derby.
One year we beat United 2-2 at Old Trafford, with Darius Vassell and Benjani scoring us. That means that the City's fans will always remember us – even if anyone else has forgotten them.
That game was 50 years since the Munich disaster, so both were wearing retro packs with no sponsors. I believe that that was the first to win City in Old Trafford for a long time so it meant a lot.
It can be hard for the center to keep control because tensions are so high. On the times that Unita is expected to beat us, if they did not win then the frustration would boil over.
One too, Cristiano Ronaldo was sent away. He had already ordered for a foul, then he was ordered again for holding the ball when he came into a corner. Your mind can go empty in a game like that – that's the derby for you.
And with what happened in mid-week games, I do not think that United will be afraid of anything on the city on Sunday.
I was in the City game in the Champions League on Wednesday and what impressed me was how difficult they were. How fast are they coming back? At one stage they were 4-0 up but they all turned back after they scored.
But it's still hard hard for the City. Two years ago he hit 0-0 in one of the worst games of all time, last season, City was on their way to win the league but United had a real decision not to lose it, and # 39 ; the fact that City has not won at home in the derby in a few provokes them on Sunday.
United has done a long way to City so they have a scheme that works for them when they go to Etihad. It is not important that it is important for United to return to the title race but they must open it.
If they can win the city away, then other teams can do that too.
When you watch City Play, and the number of goals that they score, it's hard to see anyone stopping them, so United will have a plan to do that this weekend. They park the bus if they have to, but they will still be very lucky to keep the City scoring.
