Arsenal had to dig deep to overcome a determined Watford side at the Emirates in an action-packed game as Craig Cathcart's own goal and Mesut Ozil's strike sealing the win for the Gunners.
As the first half progressed Unai Emery's side grew into the game and should have had a penalty when Christian Kabasele caught Lacazette, the Frenchman's honesty perhaps costing his side. The former Lyon striker then missed a golden opportunity to put his side ahead when through on goal, dinking wide of the right hand post.
The second half continued in the same light with both sides creating chances.
