Laurent Koscielny will miss the FA Cup final after being sent off in Arsenal's clash with Everton for horror tackle on Enner Valencia

Arsenal will take on Chelsea in the FA Cup final without centre back Laurent Koscielny after the Frenchman was sent off on the final day of the Premier League season.

Koscielny - an integral part of the Gunners' backline - was given his marching orders 14 minutes into the game against Everton following a horror tackle on Enner Valencia.

The straight red card brings with it an automatic three-match ban, ruling the defender out of the Wembley showpiece clash with Chelsea and the opening two games of next season.
