Arsenal and Chelsea shared a moment of silence before the FA Cup final to remember the victims of the Manchester terror attack.

LONDON — Chelsea forgot to wear black armbands for the first half of Saturday’s FA Cup final against Arsenal at Wembley after a dressing room mix-up, sources have confirmed to ESPN FC.

A minute’s silence was held prior to kick-off as a mark of respect for the victims of Monday’s terror attack at Manchester Arena that killed 22 people and injured more than 100, with Prince William, Football Association chairman Greg Clarke, Manchester mayor Andy Burnham and Culture Secretary Karen Bradley laying commemorative wreathes pitchside.

But Chelsea’s players did not take to the field wearing black armbands as arranged after the FA Cup jackets they wore coming out of the tunnel were placed on top of them in the Wembley dressing room.

Club officials quickly realised the accidental error and instructed the players to put on the armbands before the start of the second half, which they did.
