Premier League football is well and truly back! The opening fixture was a tense encounter that eventually saw Arsenal come from behind twice to beat Leicester City 4-3 at the Emirates Stadium on Friday night.New signing Alexandre Lacazette opened the scoring for the Gunners with only his second touch (first from kickoff) in the second minute but Shinji Okazaki equalised minutes later. Jamie Vardy then made it 2-1 before Danny Welbeck equalised at the stroke of half-time.Vardy made it 3-2 off a corner 11 minutes into the second half before Arsene Wenger made a few substitutions and had players in unorthodox roles. But it seemed to work as substitutes Aaron Ramsey and Olivier Giroud scored within two minutes of each other to give Arsenal the 4-3 win.Here's how Twitter reacted to the game.6 - #ARSvLEI was only the 6th game to see seven goals scored on the opening matchday of a @PremierLeague season.

Impact. #ARSLEI pic.twitter.com/f7qhkYvbul— OptaJoe (@OptaJoe) August 11, 2017Lacazette has set the bar so high by scoring on his debut. Now Lukaku and Morata have no otherwise.

That's right to left, by the way. Ugh— Oliver Kay (@OliverKayTimes) August 11, 2017Arsenal reshuffle means they now have a midfielder at right-back, a right-back at left-back and two left-backs at centre-back.— Tom Williams (@tomwfootball) August 11, 2017I've never seen a Premier League team play more players out of position at one time. Laughable— Frankie Hobbs (@Frankie_Hobbs) August 11, 2017Arguably the entire back four, Welbeck and Lacazette are all playing out of position. That's 6 of 11.— gunnerblog (@gunnerblog) August 11, 2017#Arsenal with a revolutionary, inverted, false back-four. #ArseneKnows— Rohith Nair (@RohithNair) August 11, 2017pic.twitter.com/OC2KcMen9M— Sultan (@WMFormation) August 11, 2017A guy caught in bed with another woman defends better than Arsenal does— Damsel in This Dress (@secondofhername) August 11, 2017*THEO WALCOTT GETTING BORN*NURSE TO PAPA -"MUBARAK HO OFFSIDE HUA HAI"— Arsenal Hindi (@ArsenalHindi) August 11, 2017Sky's new player graphics look like the loading screen to a triple threat match on Smackdown vs Raw 2007 pic.twitter.com/yx9E8Ob8qf— Robbo (@RobV96) August 11, 2017Last time I took my mum to Leicester game Welbeck scored in last minute and she told me to f**k off.
