Arsenal will play London rival Chelsea in the FA Cup final on May 27 after beating Manchester City 2-1 following extra time in the semifinal at Wembley 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 equalized 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 seems 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 trails league leader Chelsea, which beat Tottenham Hotspur 4-2 in Saturday's semifinal, by 11 points with six games to play going into a big game Thursday against local rival Manchester United, which is fifth, one point behind them. Benteke comes back to haunt Liverpool Liverpool old-boy Christian Benteke stunned his former club with both Crystal Palace goals in a 2-1 win at Anfield Sunday denting the home side's top-four Premier League ambitions. Benteke handed a massive boost to Palace's survival hopes with a goal in each half to cancel out Philippe Coutinho's brilliant opener for the Reds and turn the game on its head. Liverpool paid £32m for Benteke when it signed him from Aston Villa in 2015 but sold him to Palace for £27m a year later. The 26-year-old Belgian made them pay for that decision with goals in the 42nd and 74th minutes that moved Palace seven points clear of the Premier League relegation zone. But defeat left Jurgen Klopp's side in third place just two points clear of fourth-placed Manchester City and three ahead of Manchester United in fifth. Both Manchester clubs have two games in hand in the scrap for Champions League places, meaning Liverpool's fate is no longer in their own hands. Earlier, Wayne Rooney scored on his return to the Manchester United starting-line up as Jose Mourinho's side enjoyed a 2-0 win at Burnley. After a week in which United lost top scorer Zlatan Ibrahimovic and Argentine defender Marcos Rojo to serious knee injuries, the return of Rooney to the side and to scoring form was a much-needed tonic. Rooney, who last started a game on March 4, was given the start for only the second time in 2017 with Mourinho opting to start with in-form 19-year-old Marcus Rashford on the bench. It was Rooney's French strike partner Anthony Martial who opened the scoring in the 21st minute.
