Arsenal crashed out of the FA Cup as substitute Lewis Grabban came off the bench to fire home a deserved winner for Nottingham Forest and seal a huge 1-0 victory over the Premier League giants.
Fifteen minutes after coming on as a substitute, Grabban tapped home an exquisite cross with seven minutes remaining to send City Ground into ecstasy and his side into a deserved lead.
Only twice since 1956 has the Gunners crashed out of the FA Cup in the third round. And Arteta will be ruing a succession of missed opportunities with Nketiah especially guilty of missing several huge second-half chances.
