Enzo Perez coming off. Fernando Gago coming on.
That's all of Argentina's three subs. Germany about to use their final one as well.
Mario Götze set to come on, most likely to replace Klose.
Yep. It's Klose coming off. Playing in his second World Cup final. 16 goals in four World Cups - the most goals in World Cup history.
Germany camped in their own half and get over halfway before turning the ball over. For a third straight time the World Cup final is set to go into extratime.
Three minutes of injury time to be played.
Mario Gotze with a long distance strike but not enough on it and it rolls straight to Romero.
Thomas Mueller with a cross but cleared. No Argentina on the break
But Agüero can't get a cross in as Hummels makes the tackle.
Whistles in the crowd. They want 30 more minutes
So 30 minutes more. The last time Germany went to extra-time in a World Cup final was 1966 at Wembley.
At least we have goalline technology now.
Match stats for the 90 mins.
Shots -Germany 8 Argentina 5
Shots on goal - Germany 5 Argentina 1
First half of extra-time underway.
André Schürrle with a shot inside the box but straight at Romero. Wow. That could have been the lead right there. He fell over, got back on his feet to receive the ball and fire in the shot, just couldn't get it past Romero.
Germany back on attack now.
Schweinsteiger with cross but Argentina clear then break.
Sergio Agüero with a shot across the face of goal. No one with him though and Germany clear. Fast-paced start to extra-time.
Both teams out to win the game. Great to see.
Kroos with a searching low pass into the box but can't find a teammate. Argentina clear.
Gotze tries to chase down a ball but it goes over the touchline.
Rodrigo Palacio with a chance inside the box but can't get a clear shot away. From his chest the ball was bouncing and he tried to chip Neuer but couldn't find the back of the net. Gaps opening up in both sides now.
You'd think Germany have the slight edge since they played their semifinal a day earlier, went easy in the second half against Brazil while Argentina went through 120 minutes against the
Germany enjoying decent territory but Argentina continue to hold strong at the back. Would be an amazing showing to go through 450 minutes in second stage of tournament without giving up a goal.
Bastian Schweinsteiger is down. But after a little break he's back up.
Javier Mascherano now goes down after clashing ith Toni Kroos in midair.
Couple of minutes left in first half of extra time.
Lahm down the righthand side tries to find Kroos on edge of box but Argentina clear.
Argentina break but Germany get freekick as Palacio fouls Lahm. And that is halftime of extra time.
So 15 minutes away from penalties. Still 0-0. An entertaining first half of extra time with Schürrle coming closest to break the deadlock. Palacio also with a chance for Argentina as he failed to chip Neuer. Players are beginning to tire, which is understandable since it's the last game of the tournament.
Argentina to start the second half of extra time. Here we go for the final time in 2014.
Hopefully if there is a goal it is down to some brilliance not an error.
Germany with possession and they get a freekick about 40 metres out.
Kroos sends it in but Argentina clear.
Some clever work by Germany as Ozil chips the ball over a defender but then loses the ball. Germany get a freekick though up the field as Agüero fouls Schweinsteiger.
Schweinsteiger is bleeding from under the eye. He'll need a quick patch-up as Germany are down to 10 men.
A clash of heads in the box between Mueller and Demichelis as Argentina get the freekick.
Schweinsteiger still off the field.
