Liverpool should have been awarded a penalty against Arsenal after Alexander Isak was pulled back by Jurrien Timber, the Premier League's Key Match Incidents Panel has ruled.

Isak just failed to get his head on the end of a cross by Bradley Barcola in the 21st minute of the game at Anfield on 1 November.
