It marked Unai Emery's biggest Premier League victory this season, with Mesut Ozil and other forwards getting their names on the scoresheets. Emery's side has frequently found themselves being criticised for unconvincing and narrow victories over weaker opponents such as Southampton and Huddersfield, but this time around, they proved otherwise.Things started off brightly for the Gunners with Ozil leaving his mark in the fourth minute of the match. The German had been left out of the team on multiple occasions this season, but in the last few games, he has found himself back in the starting XI. His impact has been felt by everyone on the team. Ozil further emphasised his importance when he laid an assist for Henrikh Mkhitaryan to double Arsenal's lead.The Gunners went into half-time with a scoreline of 2-1. Just as Bournemouth thought they had a chance to turn things around, Laurent Koscielny netted Arsenal's third goal. It was a huge game changer because that goal dampened the Cherries' confidence and empowered the Gunners to exert more dominance. Eventually, Pierre-Emerick Aubameyang and Alexandre Lacazette both scored to make it 5-1 against Bournemouth.It was a fine game for Emery's team who will face Tottenham at the Wembley Stadium over the weekend. Fans will be eager for their side to seek revenge against the Lilywhites since Tottenham had dumped Arsenal out of the Carabao Cup earlier in the season. The manager's main concern will probably be the extent of the knee injury that Koscielny suffered towards the end of the game. While the captain stayed on for the remaining minutes of the match, he looked to be in some discomfort. If Arsenal were to lose him to injury ahead of the North London Derby, it will surely have an impact on the overall performance of the team. Here was how fans celebrated the big victory in Premier League.👏 Arsenal record their biggest home win under Unai Emery.

Last time we won by that scoreline fans sang “we’ve got our Arsenal back. That turned out to be very premature.However, it is beginning to feel a bit like at least Unai Emery is getting HIS Arsenal back. We’re moving in the right direction once more.
