No card was shown to Ryan Christie for this challenge on Bukayo Saka

Arsenal maintained their Premier League title hopes with an encouraging 3-0 win against Bournemouth.

Controversy marred the game, however, with Ryan Christie not penalised for a high challenge against Bukayo Saka early on.

Bournemouth can also feel aggrieved after they had a call harshly chalked off for a foul on David Raya.
