Laurent Koscielny fails in bid to have suspension lifted for FA Cup final

Arsene Wenger also has fitness concerns over two defenders.

Arsenal's Laurent Koscielny is to serve a three-match suspension after his appeal against his sending-off in Sunday's win over Everton was dismissed by the Football Association.

The 31-year-old received a straight red card for his reckless first-half challenge on Enner Valencia and will therefore miss Saturday's FA Cup final against Chelsea and the first two domestic fixtures of next season.
