Arsenal boss Arsene Wenger admits they're at bare bones for the FA Cup final against Chelsea on Saturday.

Laurent Koscielny's red card against Everton and Gabriel's injury give the manager a headache ahead of the game against Chelsea.

With Shkodran Mustafi also a doubt, it leaves Wenger with plenty to ponder ahead of the match at Wembley Stadium.

“It just shows you how unpredictable football can be because we played at home, your mind is on attacking, and on the day we lost two centre backs," the manager said.

“It's absolutely unbelievable and unpredictable, and we have been hit hard in a position where we will need to be strong on Saturday. We'll have to find solutions and hopefully I will find the good solutions.

“I have to decide until Saturday [whether to keep a back three or not] - we'll test that in training until then."
