United got the better of Premier League rivals Palace 2-1 after extra time in the final of the FA Cup at London’s Wembley Stadium.
The Red Devils’ victory means that West Ham have booked a spot in the Europa League next season.

West Ham are not guaranteed a place in the group stage of the Europa League next season.
The London outfit will enter the prestigious European competition at the third round qualifying stage.
However, the fans should be jubilant that there is a very good chance that they could get to see 'proper' European football at their new stadium next season. West Ham are leaving the Boleyn Ground for the Olympic Stadium.
