Mexico fans have been watching the game in their thousands in Mexico City's main square, the Zocalo. Imagine their reaction when Dos Santos banged in the opener. Scenes.

Mac Jerry:, external Totally deserved. Had to be Giovani Dos Santos.

Chris Baldwin:, external Still can't believe Dos Santos couldn't even get on the Spurs bench. He looks some player now.

That loan spell at Ipswich seems a long time ago...

Almost a second for Mexico. The Dutch are rocking as they concede a free-kick on the right, with Rafael Marquez heading the set-piece over the crossbar.

"Netherlands are in big, big trouble because they have to up the pace of their game now. What a hit. He caught it perfectly, brilliant goal. Over the period of time in this game it is deserved. Boy have we got a game on. What will Louis van Gaal do now? The system has not been working. They have generally been second best in this game and Van Gaal has to change it now."

Breakthrough! Giovani Dos Santos wakes everyone up with a rocket of a strike. The Villarreal striker holds off a posse of Dutch defenders before thumping one into the bottom corner. Cue manic Mexican celebrations down near the corner flag.

"As the sun moves around the stadium everyone is moving into the concourse to get out of the sun, I don't think I have ever seen that at a stadium before."

Alexander:, external I think Louis van Gaal is playing a clever game - wear Mexico down and add a player like Memphis Depay late on. His blistering pace could change the game.

Dave:, external Wesley Sneidjer has been poor in this tournament. Yet to see a single killer pass from him. Surprised he's kept his place.

Stepan Benyovszky:, external Netherlands are already looking like they've played 120 minutes. They'll need something special and a heap of luck.

All systems go. We have got a minimum of another 45 minutes to find a winner. If not we go to extra-time and then - gulp - it's the dreaded penalty shootout.

Miguel Herrera is a man who loves a good facial expression. I can imagine his team-talks are pretty lively as he scribbles away at his tactics board. He has been forced into one change at the break as Hector Moreno cannot continue after that late injury. Porto defender Diego Reyes gets his chance.

Jon, Brentwood: Netherlands have been sitting back, conserving energy, will be an interesting second half. Hope there's an early goal.

Dave P, Newcastle: Sedentary stuff. Not the fault of the players, so difficult in that kind of heat and humidity. Doesn't bode well for Qatar.

Dave, Ealing: So we can have three-minute water breaks but can't review a penalty decision in 30 seconds?

Interesting to see that one of the stands running along the Fortaleza touchline is pretty empty. Nothing to do with the quality of football - more the unbearable heat. Most of the sweating fans have dashed back into the concourse to cool down and watch the action from the shade.

"A sense of disappointment in the stadium at half-time. The heat, as you well know, has been a huge factor. Mexico started very well indeed but the Dutch have started to find a way to cope simply by keeping the ball and relying on the brilliance of Robin van Persie and Arjen Robben to pinch them something at the other end. By the time the second half begins a third of the pitch will be in shade. Perhaps that will bring the Dutch out of their shells?"

Luke:, external Any other player than Arjen Robben and that's a penalty. His pathetic diving all tournament and in this game has come back to bite him.

"It has been a very good game. The entire Mexico squad is around Hector Moreno now. to see if he is OK. The discussion will be the penalty, should it have been one? The more I see it the more I think it was a penalty. Netherlands probably realise they are quite fortunate not to be behind, though. If Mexico can get one of their chances to fall to Oribe Peralta, that might make a difference."

But that last-ditch tackle has come at a cost for Moreno. The Mexico defender grimaces as he is lumped on to a stretcher and taken off the pitch. He has not been substituted as he has another 15 minutes to recover.

Looking again at the replays of that Robben incident - do the Dutch have claims for a penalty? Maybe. Hector Moreno steams in from the other side of Marquez and may have swiped Robben's legs.

'Ole!' cheer the Mexican crowd as their team stroke the ball around confidently. Uh oh - they have almost spoken too soon. Francisco Rodriguez sells Rafael Marquez short with a hospital pass and the Dutch race clear. But Marquez's ageing legs find some pace from somewhere and nips in to deny Arjen Robben.

The wilting Dutch take the sting out of the game, passing backwards as they look to conserve their energy. That doesn't go down with the booing Mexicans in the crowd. Four minutes of injury-time - including the three minutes for the earlier cooling break.

Another Mexican chance goes begging. Giovani Dos Santos finds space at the far post but his low shot is blocked by a big right hand from Netherlands stopper Jasper Cillessen.
