Arsenal captain Laurent Koscielny has been hit by a new injury scare.

He is a doubt for the North London derby with Tottenham after suffering an injury two minutes before the end of the win over Bournemouth.

The sight of their best centre-back limping off the pitch will be of major concern for Unai Emery, who watched with an anguished look while his player received treatment for two minutes.

After the match, Emery said: "I hope it is just one kick. He has three days between Saturday and I hope he will be OK."

Koscielny put in an impressive display at the Emirates as the Gunners thumped Eddie Howe's men 5-1.
