Second-placed Arsenal missed the chance to cut Manchester United's lead at the top of the Premier League table after two last-gasp penalties that saw Liverpool grab a 1-1 draw on Sunday.
Robin van Persie slotted home for Arsene Wenger's side in the eighth minute of added time after Jay Spearing brought down Cesc Fabregas.
Liverpool were then handed a dramatic late penalty of their own after Emmanuel Eboue fouled Lucas Leiva and Dirk Kuyt converted.
Liverpool, who have not won away at Arsenal since 2000, had Jamie Carragher carried off on a stretcher after a clash of heads early in the second half.
Arsenal now trail United by six points with six games remaining.
Stoke in FA Cup final
Stoke City stormed into their first ever FA Cup final after a first-half goal spree inspired a 5-0 win against Bolton in Sunday's semifinal at Wembley.
Tony Pulis's side will face Manchester City in the final on May 14 after three goals from Matthew Etherington, Robert Huth and Kenwyne Jones in the space of 19 minutes destroyed Bolton before the match had even reached half-time.
Jonathan Walters capped Stoke's perfect day with two more goals after the interval. Stoke were appearing in their first semi-final in the competition since 1972, the year they also won their last significant piece of silverware when they beat Chelsea in the League Cup final.
