Arsenal are unlikely to be punished by the FA after Dele Alli was struck with a water bottle thrown from the stands at the Emirates.
The Gunners are scouring CCTV to try and identify the culprit.

Alli was struck after scoring Spurs’ second goal in their 2-0 win over Arsenal in the EFL Cup quarter-final.
