The defeat to Manchester City set this bad record for Manchester United

Manchester United suffered a disappointing defeat at the hands of their crosstown rivals, Manchester City, in the FA Cup final, handing Guardiola's side their second trophy on their path to a treble. 

Losing a final to their neighbours, who are on course to equal an achievement only they can lay claim to in the English top flight, was not bad enough; the defeat also saw them set a gloomy record. 

In the opening minute of play, Ilkay Gundogan gave Manchester City the advantage until Bruno Fernandes equalised from the penalty spot in the 33rd. 

The German would have the last laugh, beating De Gea with a shot through a mass of defenders to give City the lead again in the 51st minute, which they would hold onto to win the match. 

The defeat today is the Red Devils' ninth in the final of an FA Cup, the most in the competition's history.

They hold the joint record for finals reached with Arsenal (21), but the Gunners have been triumphant 14 times (the most), while United are behind them with 12. 

Meanwhile, Manchester City boss Pep Guardiola declares their intent to win the treble following the victory over Manchester United in the FA Cup final.
