Consecutive Premier League defeats to Manchester City and Chelsea were followed by seven straight wins, putting the Gunners within two points of the summit; and results elsewhere have been just as impressive.
Unai Emery's side have had to overcome a hard start to the 2018-19 campaign and, now, grabbed a 10th consecutive victory with Leicester City comeback win on Monday night. "When you continue to improve your demands are very high. We're only thinking of each match". Also each player can help us with their quality or their capacity.
With this win Arsenal are now at the 4th spot in the Premier League table.
Though Arsenal carried the momentum into the second half, it was Leicester which nearly regained the lead as Wilfred Ndidi's header hit the crossbar.
Three minutes later the hosts went 3-1 up, this time after more magnificent team play orchestrated by Ozil, who set up the Gabonese striker to seal the deal for the Gunners. With a trip to face Crystal Palace on Sunday afternoon to come, Emery is likely to make several changes to his team - even if this appears to be the most hard of Arsenal's group-stage matches.
Ozil appeared to embrace the role as the World Cup victor led by example to help Arsenal to bounce back from an early own goal to ease to a resounding 3-1 victory.
"Yeah", Emery said. "For Mesut, today was a very good performance, and a very good victory together". We had the opportunity to score goals, we looked very risky going forward. We look at Leicester, they are a very good team.
Leicester City lose their second game in a row after a dominant second half display from Arsenal on Monday evening.
Wilfred Ndidi hit the crossbar for Leicester with the scores level in the second half and was also the closest player to Rob Holding when the Arsenal defender got away with a clear handball inside the box early in the game.
The euphoria of taking a 1-0 lead courtesy of Hector Bellerin's 31st-minute own goal was replaced by the disappointment of conceding just before half time, with Pierre-Emerick Aubameyang's second-half brace enough to see the points stay in north London.
