"We did say earlier that there will be times in the game when Reading will be able to sit off and coast for periods, trying to conserve some energy, but when they have got in Arsenal's face they have been committed and the plan has worked perfectly. The only question now is will fatigue kick in?"

"Arsenal have been very disappointing today. Reading will have to work hard as Arsenal will have a lot of possession in extra-time, but Reading do deserve something. Once again when Arsenal are overwhelming favourites they do not get out of the blocks quick enough."

Here is his touch map. More touches than anybody else.

We go on.

Arsenal fans, penny for your thoughts. Championship opposition at this stage a year ago, extra time needed, second tier opponents again, same outcome.

What a brave Reading display in the second period.

Last chance. Free-kick Arsenal swung in by Santi Cazorla and Olivier Giroud can only head into the hands of Adam Federici.

Two minutes added on.

Chance again for Arsenal and it's Aaron Ramsey with the opportunity to win it for the Gunners. It was tougher than his previous one but a good one nonetheless. Kieran Gibbs makes progress down the left and crosses for the Welshman who can only divert over the bar. Big chance.

In fairness to Pavel Pogrebnyak, on first sight he could have used the two versus one advantage but Jamie Mackie looks so leggy he barely made a run for him.

This is pulsating stuff. Pavel Pogrebnyak on the ball, midway into the Arsenal half, it's a two versus one situation but he will go alone and his touch is poor and costs the Royals a golden chance.

What an end to this 90 minutes.

"What a fantastic counter attack to break through the middle of Reading's defence. I thought Aaron Ramsey was going to go down at first but he stayed on his feet and I thought his shot was in - like everyone did. How did he hit the post?"

I just said Aaron Ramsey was quiet. The crashing sound his shot against the post just made has shaken me to my boots.

What a chance, some may say what a miss. The midfielder bursts forward to collect a pass and is in behind the Reading defence, inside the area, goal at his mercy , his first shot is saved but as the rebound falls and the angle narrows, he smashes the woodwork from six yards.

Nathaniel Chalobah cuts in from the left flank and has a dip... it is a dip indeed as the ball moves in the air and Wojciech Szczesny has to dive to his right to save well.

"Arsene Wenger looks very frustrated. He's walking up and down the touchline as if to say, how are we drawing this game? Steve Clarke is shouting at his team, barking orders for them to keep their shape."

Santi Cazorla on 90 touches is undoubtedly the man who makes Arsenal tick. He starts another attack, caressing the ball wide to Kieran Gibbs. Aaron Ramsey has been quiet and he tries to bulldoze his way through Reading. No way through Rambo. Not even with a nickname like that.

Jamie Mackie is wrestling with a defender, a mini war, the ball breaks free and Pavel Pogrebnyak will drive at the Arsenal area, he again shows decent pace but a left-foot strike from a tough angle will dribble across goal.

If Arsenal progress today they will top the list for FA Cup final appearances on 19.

Steve Clarke is pointing and yelling at his troops from the touchline to make sure that doesn't happen, and here they come again...

Jamie Mackie pumps up the Reading fans with a war cry, not that they need it. What a display they have produced in this second period. Much more of the ball with far more intent.

Can Arsenal get Olivier Giroud into the game? THEY CAN... but Alexis Sanchez puts too much on his return pass and the Frenchman will not catch that.

"Gabriel has to hit the target from there. He was only six or seven yards out - that header has to go in."

Wow. Gabriel may have the name of an angel but this effort is anything but heavenly. The substitute somehow ghosts into space as Mesut Ozil delivers a free-kick, he must score, unmarked, eight yards out, just glance it... he gets too much of the ball and it's high and wide.

This competition continues to throw up absorbing games this year and with 18 minutes left, where is this latest drama going?
