PREM: Arsenal 2-0 Watford

Mesut Ozil of Arsenal celebrates scoring his sides second goal.

Craig Cathcart's own goal and a Mesut Ozil second gave Arsenal a flattering 2-0 victory over Watford for a seventh win in a row.

Alexandre Lacazette's pressure on Cathcart saw him turn Alex Iwobi's cross beyond Ben Foster with nine minutes to go at the Emirates, before which the visitors had enjoyed the better of the chances.

Will Hughes had volleyed an early chance wide, Andre Gray had a one on one saved by substitute goalkeeper Bernd Leno and an Isaac Success effort glanced the post with the scores goalless.

But once unconvincing Arsenal went ahead they quickly added another, Lacazette turning provider and Ozil firing home (83) to give Arsenal a seventh consecutive win, and fifth in the Premier League.

Watford's confidence has not been shaken since their perfect start to the campaign was ended by a draw and a defeat from their last two games, and they pressed Arsenal from the off at the Emirates.

But they could have been behind within five minutes, when Christian Kabasele's cumbersome challenge in the box caught Lacazette. The forward gallantly tried to stay upright but stumbled over a second later - and it was enough for referee Anthony Taylor to wave for a goal kick.

Hughes failed to take advantage of that let-off when he planted a volley wide from the edge of the box minutes later, when he should have found the target given the time he had to shoot.

An end-to-end game ebbed and flowed but Arsenal spent much of the game lacking imagination, and their best chance of the half came from a Watford mistake when Lacazette caught Cathcart in possession, before racing through and missing the far corner.

Petr Cech was forced off with a hamstring injury just before half-time and his replacement Leno needed to be in good form after it, denying Deeney's toe-poke from a Jose Holebas free-kick with a brilliant diving save.

It was his decisiveness rather than his reflexes which would then thwart Gray, when he raced off his line to narrow the angle when the striker was played through one-on-one and shot straight at him.

But he was nowhere near keeping out Success' effort when the Arsenal defence again went to sleep and allowed him to find space in behind, and was relieved to see the forward's dinked effort brush the far post before going out.

Arsenal's sighs of relief soon turned to cheers of delight when Iwobi's cross struck Cathcart's leg and bounced into his own goal, before Ozil doubled the lead from a rapid break with the visitors pushing forward for an equaliser.

 Troy Deeney showed his excellent link-up skills, making a number of chances and using his strength well.

Those goals extend the Gunners' winning run under Unai Emery for their longest run of Premier League victories since August 2017, but for the second weekend in a row their performance did not live up to the result.
