Welbeck scores as Arsenal beat West Ham

Arsenal recorded their first Premier League win under new manager Unai Emery after Issa Diop’s own goal and Danny Welbeck’s late strike saw West Ham fall to their third straight defeat.

The defensively frail Gunners also lost their attacking fluency following the break but went ahead fortuitously as Alexandre Lacazette’s volley across the area deflected in off Diop.

Hector Bellerin then picked out an unmarked Welbeck in added time and the substitute turned to lift his effort past Lukasz Fabianski.

West Ham captain Marko Arnautovic put the visitors in front on 25 minutes, exchanging passes with the impressive Felipe Anderson before slotting low past Petr Cech.

Nacho Monreal equalised five minutes later, firing into an unguarded net after Bellerin’s cross deflected into the defender’s path off Alex Iwobi.

Both Arnautovic and Robert Snodgrass then shot straight at Cech as the Hammers missed several chances to take the lead again, with former Gunner Lucas Perez also slicing wide late on in search of an equaliser.

The Hammers drop to bottom of the Premier League, while Emery’s first win since replacing Arsene Wenger in May moves Arsenal up to 11th.

Frail Arsenal need defensive improvement

The first half at times resembled a contest to determine which side’s defence were more inept, with Arsenal edging it.

Their tactic of playing out from the back with Shkodran Mustafi and Sokratis Papastathopoulos split either side of Cech was too easy for West Ham to disrupt, particularly with neither centre-back looking mobile enough.

It led to several chances for the visitors, as did having full-backs Monreal and Bellerin pushed high – the latter especially offered plenty of threat going forward but it meant West Ham had plenty of space to counter-attack into.

Anderson exploited that space brilliantly throughout, driving at the Arsenal defence before playing a one-two with Arnautovic through Mustafi’s legs and allowing the striker to pick his spot in the bottom corner from outside the area.

Elsewhere, Arsenal failed to pick up runners, with the offside Arnautovic wisely leaving Michail Antonio’s through ball for the overlapping Snodgrass, only for the Scot to pick out Cech.

The hosts escaped with a win here but better sides will both carve them apart and finish their chances if the defending does not improve.
