Arsenal will play London rivals Chelsea in the FA Cup final on May 27 after beating Manchester City 2-1 following extra time in the semi-final at Wembley on Sunday.
Arsenal had to come from behind after Sergio Aguero scored his 30th goal of the season for City in the 62nd minute, racing on to a pass from Yaya Toure.
Spanish international Nacho Monreal equalised nine minutes later, from a cross by Arsenal's other wing back Alex Oxlade-Chamberlain.
In the 11th minute of extra time, just after Aguero was taken off, Alexis Sanchez scored the winner.
The result gave Arsenal manager Arsene Wenger, an FA Cup winner six times, a welcome boost in a season that many supporters would like to be his last at the club.
Arsenal seem likely to miss out on a top-four finish in the Premier League for the first time in 21 seasons under Wenger but winning a third FA Cup in four years could well persuade him to defy his critics and sign a new contract.
"I'm very proud of our performance and the spirit we've shown," the Frenchman told BT Sport.
"We gave a good answer to people who questioned that."
Manchester City manager Pep Guardiola's record of having won at least one trophy in every season as a manager is almost certain to be ended.
City trail league leaders Chelsea, who beat Tottenham Hotspur 4-2 in Saturday's semi-final, by 11 points with six games to play going into a big game on Thursday against local rivals Manchester United, who are fifth, one point behind them.
CITY UNCHANGED
In his 50th City game, Guardiola picked an unchanged side for the first time and they were the more threatening in a dull first half despite having to replace the injured David Silva with Raheem Sterling.
Shortly before the interval they were unluckily denied a goal when an assistant referee ruled -- incorrectly it appeared -- that Leroy Sane's cross had drifted out of play before Aguero and then Sterling put the ball past Petr Cech.
In a much livelier second half Toure robbed Aaron Ramsey and sent Aguero away from the halfway line for the Argentine to dink the ball past Cech for his 12th goal in as many games.
The equaliser arrived from a less regular scorer. It was full back Monreal's first goal for two years.
Toure's volley and Fernandinho's header both hit the frame of the goal in the space of four minutes but early in extra time a weary Aguero went off and within two minutes Sanchez scored from close range after Danny Welbeck missed his kick.
Guardiola blamed City's wayward finishing for the defeat.
"We competed here, we had more chances but the finishing was like it has been throughout the season," he said.
