But still, in the first half we had a good chance through Alexandre Lacazette, and I said to him the most important thing is to be creating these chances, and then we will score goals"Unai Emery, Arsenal head coachWatford toiled hard through the 90 minutes, but lacked the finishing and the luck to get a result from the encounter."We had more chances more clear chances, more shots, more shots on target, and feel really good but at the end we didn't deserve the result.I think all the players put in a very good performance, and I'm pleased with the attitude of my players and with the performance as well. I think we can be only proud of them for keeping a good level and competing in all the games and deserving more. But I'm sure in future we will get it."Javi Gracia, Watford head coachLet us look at three reasons behind Arsenal's victory on Saturday:#3 Solid display by the goalkeepersBoth of Arsenal's goalkeepers played a big role in their victory against WatfordThe North London side needed both their goalkeepers to keep a clean sheet against the Hornets. Petr Cech, who has started all of Arsenal's matches in the league this season, made a couple of important saves in the first half.However, the veteran goalkeeper had to be substituted after pulling his hamstring in the 45th minute. Effectively, German international Bernd Leno made his Premier League debut for the Gunners and dished out an impressive performance in the second half.The 26-year-old made three important saves that were pivotal in keeping Arsenal in the tie. He looked commanding in the box, dealt well with set-pieces and returned three successful long-balls in his 45-minute performance. Overall, it was a memorable league debut for the Bayer Leverkusen recruit.Really good save from Leno to deny Deeney pic.twitter.com/c9ZG0657ZW— Terje (@ArsenalTerje) September 29, 2018
