Arsenal moved back into the Premier League top four with a 1-0 win over Watford at Vicarage Road.
Pierre-Emerick Aubameyang scored the only goal of the game, capitalizing on a howler from Hornets keeper Ben Foster whose botched clearance ricocheted off the Gabonese and into the back of the net.
Watford striker and skipper Troy Deeney was given his marching orders shortly afterwards having been adjudged to have deliberately elbowed Lucas Torreira in the face.
But the hosts had their chances to equalize – only to be denied by an inspired display by Bernd Leno in the Arsenal goal.
Here are the player ratings …
Foster 5 – Fine season stained by horrendous mistake to gift Arsenal lead
Janmaat 7 – Rampaging runs forward gave Watford hope against the odds

Cathcart 7 – Never threw in towel and his low shot hit the post
Femenia 6 – Provided width and energy but few crosses picked out team-mates
