What a game we were served. What a display by the underdog - a recurring pattern in the FA Cup this season. And what a moment of calamity to decide things.

Former Reading striker Jason Roberts tweets:, external Gutted for Adam Federici there is not a better man you would want fighting alongside you..I am proud to call him my friend...

Who do Arsenal fans want to face in the FA Cup final on 30 May?

Sho:, external Villa. Cannot stand Liverpool fans. Besides, Villa could do with a cup final considering the season they have had.

Reading boss Steve Clarke: "It's not a case of being robbed, it's about getting what you deserve from the game. The effort and the tactical and technical discipline was there. You feel for Adam Federici, this is the life of a goalkeeper. The big mistake. If you lose, you want to lose to a moment of brilliance not a mistake. But I'm sure if you did a shortlist of top three players at Reading this season, he would be up there. I told him [after the game] to keep his head up. The mistakes will freshen his mind. We win as a team and lose a team."

Former Reading chairman Sir John Madejski talking to the BBC: "I'm so proud of Reading and the fans must be delighted and now we have to concentrate on our league position. It's always a case of what might have been and to have lost that goal just before half time of extra time but it bodes well for the future of Reading football club and we live to fight another day.

"I think we played well above our level against an in form Arsenal. We'll be back and it's just a matter of time until we lift some silverware, we were always going to be underdogs and at the end of the day the best team won and the players and fans should be very proud."

Arsenal manager Arsene Wenger on the performance of Alexis Sanchez: "He struggled to get into the game but has that stubborn resilience and individual potential."

I'd hate to see the damage he would cause if he did get into the game.

Reading manager Steve Clarke: "It was a really good performance, I feel for the players they gave everything, feel for the supporters they gave everything. It should have been a good afternoon for us but sometimes in football you do not get reward for such a good performance.

"The second-half we grew into the game and found belief and found a bit of quality to get back into the game. It is a good job there was goalline technology otherwise I am not sure they would have given us the goal.; We should have had a penalty in the 65th minute for a handball. You need these moments to go for us.

"Federici is upset, he had made a mistake in a key game but he is a strong personality and has been magnificent for the club all season. Without his saves we would be in even more trouble at the bottom of the Championship."

Reading manager Steve Clarke tells BBC Radio 5 live goalkeeper that Adam Federici has been taken to doping control.

It's fair to say probably not what the stopper needed.

"He will be sat on his own without anyone around him," former Hull City midfielder Kevin Kilbane tells BBC radio 5 live's 606.

The two games in which Ozil has laid on two goals have both arrived since March.

The German international played 114 passes, that's more than any other player on the pitch. He completed 90.4% of them. A stellar display.

Arsenal manager Arsene Wenger says Reading were ready to "die" on the pitch, such was their effort for 120 minutes.

"It was a very difficult game against a well-organised, physical and resilient Reading team," he says. "They defended very well.

"After half-time we didn't have the same intensity in the first half. We started to suffer and paid for it.

"Reading were ready to die on the pitch to get to the final and we have to congratulate them on their effort today."

Arsenal goalkeeper Wojciech Szczęsny, who is celebrating his 25th birthday today, said: "I am happy we are through but I thought Federici was terrific today. He had the game of his life and they only got to extra time because of him. He was the best player on the pitch. I really feel for him, I have been there, done that."

Szczesny's mistake allowed Birmingham's Obafemi Martins to score the winner in the 2011 League Cup final at Wembley.

"I am pleased with the win but I am distraught for Adam Federici. I would rather win on penalties. It is something you don't get over. He has to close his legs and get his body behind the ball. It is harsh but that is it.

"What is more upsetting is when Arsenal are playing these teams they start so slowly. It is disappointing to see them play like that.

"Winning the FA Cup will be a fantastic way to end the season for Arsenal."

James.Pheney: Lucky as per usual from Arsenal. Even Neuer made a mistake like Federici a few weeks ago. Come on Reading!!!!!!

Ben Chowns-Smith: Got to feel for Federici. It was a bad error but he's still human. Hard to see someone leave the field in tears.

Zahid: Michael Hector did us all proud! What a performance! The Fresh Prince of East Ham, this won't be the last we see of him!

That last Alan Shearer entry sent a shiver through me. Imagine spending the rest of your life being reminded of your most embarrassing moment. Sport at its most brutal does not hurt you physically but will pollute your very being for eternity.

"It's not nice to see when it comes down to one individual, Adam Federici will remember that for rest of his life and people will mention it to him for the rest of his life. He actually played very well but it's agony for him, the players and the fans. But one thing Steve Clarke would have said to his players is to give everything, not to leave anything on the pitch and they did that."
