Unai Emery's tactics and influence will be called into question after his Arsenal team blew a two-goal lead to draw 2-2 with bottom-of-the-table Watford in the Premier League on Sunday.
The stalemate at Vicarage Road gave Quique Sanchez Flores a point on his return to the dugout for the Hornets. It also meant the Gunners wasted another fine performance from in-form striker Pierre-Emerick Aubameyang.
Earlier, Everton slumped to a 3-1 defeat away to Bournemouth. The Cherries got two goals from Callum Wilson, while the visitors struggled to impose themselves with Gylfi Sigurdsson again failing to pull the strings.
