When young Messi came on as a substitute and impressed the world

But look at the Argentine bench. You would not want to see Tevez and Messi coming on to finish you off in the second phase of a World Cup finals game. Scaloni rather has got away with that. Messi's coming on steel, eh? Saviola's coming off, which isn't a great surprise. 19 today, Messi. Riquelme, Messi. Three minutes will be added on to... And here's Messi. He's left Salcido. Aymar ahead of him. Tevez here. Messi for the return. Aymar. Still Messi. Malzini. Toronto. Riquelme. Beautifully in! Onside! Aymar and Messi! The flag's up! It's not going to count. The referee's assistant flagged up very, very quickly, but he's onside. When the ball's played, Steve, he's on. No question that Aymar was onside. Messi certainly wasn't. It wasn't because Aymar played it into Messi, he was in an offside position. The flag was for Aymar, and he was onside. Definitely. And it is the first time we will have extra time in the World Cup 2006. Mark Lawrenson, a magnificent, fascinating 90 minutes, and we've got 30 more to enjoy. I'm delighted. Well, yeah, and I think it's going to get even more fascinating because with the substitutions, there are now more attacking players for both teams on this pitch, and I do feel we might be a little bit cautious that second half. In case of mistaken identity, it should have been Gerardo. Gerardo who got it. Castro upsets the referee again. He'll be off through no fault of his own because he shouldn't have got that moment in the push in Mexico back. Messi. Tevez. Messi. Aymar. Messi. This is Messi. Messi. Oh, brilliant, there was a leg stuck out there. Messi, to his credit, kept to his feet, or tried to, as Osorio stuck his leg out. He's definitely inside the box. Messi for Argentina. Tevez. Couldn't pick out Messi. Messi. Riquelme to Messi. Sorin. That's a great goal! Fantastic goal! 2-1 Argentina! Drop Riquelme in as well. Take the two off. Riquelme. Messi. Aymar. Gerardo's caught it. Aymar for Argentina. How much do they want another one? How much do they want it? Get some more energy out of those legs and try and put this game beyond Mexico, or will they settle for 2-1? Maxi Rodriguez forward to Tevez. Messi. He's going to play as a centre-back. And Mendes is going to play as a right-back. We said at the start about completely changing the system, but the whole play is happening. Goal away to Scaloni. Riquelme. Messi. More than ever before he's sat in front of the back four and conducting matters, making sure that the two centre-backs don't get run at from deep. Oh, great play by Messi! Riquelme. Miquez here. Riquelme to Ainsley. Messi. Aymar to Messi. Oh, brilliant Messi again. Tevez. Aymar. Messi. What a goal this could be. Tevez just lost his footing at the crucial moment. Could finish it here, Argentina. Messi hasn't got an awful lot of support, may not need much support. Messi. Brought down by Torado. Well, he thought it was a price worth paying, didn't he? Stopped Messi, don't go. Quarter-final. Get him up on the upper arm. Messi here. Another free kick Argentina's way. Foul by Torado this time. Argentina, favourites to win the World Cup, have had to walk a tightrope here against a really excellent Mexican side. But they've scraped it, they've squeaked it, they've won it with a wonder goal from Maxi Rodriguez. Argentina will play Germany in Berlin on Friday. Mexico are a beaten side, but they have done themselves proud in Leipzig. But Argentina are into the last stage of the World Cup.
