Arsenal's Premier League title hopes suffered a huge blow with a shock home defeat as Watford secured their first top-flight win over the Gunners since 1988. Former Tottenham defender Younes Kaboul lashed in the opener within 10 minutes for Watford with a shot from outside the area which deflected off Aaron Ramsey. Just two minutes and 57 seconds later, the visitors doubled their lead as Troy Deeney tapped in the rebound after Etienne Capoue's fine run ended with his shot being saved by Petr Cech. Lucas Perez struck the crossbar with a powerful drive, but they could not find the equaliser.
