Paul Scholes: I always hoped Leo Messi would keep as far away from me as possible when we played Barca
It was a moment I will never forget. He went past me, I stuck out my leg and Lionel Messi went over.
This was at Old Trafford in 2008 in the second leg of our Champions League semi-final against Barcelona and, with the score 1-0 to us, I had fouled him in our area.
When I think about our win over Barcelona in that game, on our way to the second Champions League title of the Alex Ferguson era, I always remember that tackle.
Yes, I scored the only goal of the tie, and it was one of my better ones. But I will never forget that couple of seconds when the best footballer in the world deceived me into fouling him and I waited for the world to fall in.
It should have been a penalty, and an away goal would have won Barca the tie. But for some reason the referee didn't give it, the game moved on and even Messi did not make much of a fuss. The relief was overwhelming.
He got his own back in the end. I faced Messi four times in my career, twice over the two legs in 2008 and then, as a substitute, in the Champions League finals of 2009 and 2011, when Barcelona beat us comfortably both times.
Messi is back in Manchester next week, to face Manchester City again in the Champions League round of 16, and it is never a bad day when you can watch one of the best footballers ever pull on a pair of boots.
There have been so many superlatives to describe Messi's career that you find yourself just adding to the pile of words about him.
So these are some of the little things that you learn when you play against the man himself which you might not see on the television.
First off, he never speaks on the pitch. In fact, I don't think I ever heard him say a word. Second, you won't believe how strong he is for a little man.
I am not ashamed to admit that in the games against Barcelona I spent a lot of the time just hoping he would take up positions as far away from me as possible.
Elusive is the word that immediately springs to mind when I think about Messi. You think you have an eye on him and then - blink - he has gone, only to reappear somewhere else in space, with the ball.
When you try to tackle him you know what it is he is going to do with the ball. The problem is staying with him.
He avoids the highs and lows of football. You rarely see him go over the top in a goal celebration, just as he never gets too downhearted.
That's a quality I think that I shared when I was a player.
I have never seen a United performance with such a high level of concentration as when we beat Barcelona at Old Trafford.
For every second of that game, and the first leg at the Nou Camp, we had to be aware of our positioning, of the dangers they posed and our shape as a team as a whole.
We spent the whole week working on it with Alex and the staff. We knew exactly what we should be doing at all times. Then we had to do it over two games.
The two finals were different. In preparation, we thought less about them and more about what we could do.
We had Cristiano Ronaldo and Wayne Rooney for the first one in Rome and we believed we could hurt them. Perhaps we underestimated them.
When you prepare to play Barcelona you go through the usual weaknesses. Gerard Pique lacks a bit of pace. Javier Mascherano is not really a centre-half (the position he played in 2011).
But you can only exploit those weaknesses when you have the ball. We had 37pc possession in the 2011 game and we were used to having a lot more.
There was never any specific plan to deal with Messi, simply that whoever was nearest picked him up. Rio Ferdinand had two great games against him in 2008 but no one keeps him quiet every time.
As a finisher, there are few players as composed as Messi. When you can score as many different kinds of goal as he can, you have every reason to be confident.
People say that I played under pressure, as a Manchester boy at United where we were expected to win every week. But it is nothing compared to the pressure Messi is under, and Cristiano too. They go a game without scoring a goal and people want to know why. Not just fans either but former players who should know better. We expect it of them now and that they keep doing it is incredible.
Messi is as famous as any footballer has ever been and yet, when it comes down to it, we don't know much about him. I read that he is a family man, and likes to walk his dogs, but beyond that he's a mystery really. I like that.
Especially these days, when people's feelings about every issue are there to be read on Twitter or wherever. Keep something of yourself back. It is a strength.
I am looking forward to seeing him play at the Etihad Stadium on Tuesday and if City want a result then their concentration and focus will have to be as good as it has ever been to make sure they are in the right place at the right time for 90 minutes. It only takes a second for that little No 10 to trick you into doing something daft.
And you can't always rely on the ref not to see it.
Chelsea need trophies to be called great team
Working as an ITV pundit on Tuesday night I was surprised to hear Jose Mourinho talking about Chelsea as a "great team".
Great teams have to win trophies first, which means that Chelsea have had a great team when they won back-to-back league titles, but they are still a long way off it now.
I recognise that Paris Saint-Germain have an excellent home record in Europe. Even so, I expected Chelsea to create more chances against them this week. They had one attempt on goal, Branislav Ivanovic's header that went in.
Barcelona or Real Madrid might not have beaten PSG but they would have had more than one shot on goal.
I wouldn't rule PSG out for the second leg, especially if Zlatan Ibrahimovic decides he fancies it. I think they will score at least one at Stamford Bridge.
Nothing wrong with Rooney 'dive' at Preston
When Wayne Rooney saw Preston North End goalkeeper Thorsten Stuckmann come charging off his line on Monday night there will have been only one thought on his mind: nick the ball past him and take the foul. I did it many times in my career.
Football is about exploiting the mistakes of others, and it was clear that Stuckmann had made a major miscalculation by coming out so quickly to a ball he was never likely to reach first.
The goalkeeper was reckless but that does not mean Rooney needed to get his leg smashed to prove a point. He got out of the way.
The rules do not specify that a player needs to be touched for an opponent to commit a reckless act. It was not the most flattering tumble by Rooney but the actions of the goalkeeper meant that it was a penalty. (© Independent News Service)
