For the second weekend in a row, two goals in the space of three second-half minutes gave Arsenal a hard-earned victory at Emirates Stadium.
We weren't at our best against an in-form Watford side, but stood up to the physical challenge well, and eventually sealed all three points thanks to a late own goal, and Mesut Ozil's third in four outings.
It could have been a much more comfortable afternoon had Lacazette scored when one-on-one with Ben Foster inside 20 minutes.
The Frenchman, who could have won a penalty in the opening five minutes when Christian Kabasele appeared to trip him inside the area picked Craig Cathcart's pocket 25 yards out, then raced through on goal.
