Arsenal are tough and fierce when it comes to games on Emirates ground. Mikel Arteta is acquainted with his players and knows exactly the appropriate techniques to triggered against his opponents. Manchester United were victims of fatigue in the game, Erik Ten Hag made big mistakes this summer by not signing Alejandro Martinez replacement, he had the available funds to sign rather he was reluctant. The Red Devils were devoured by Gunners in injury time, ofcourse no one was expecting that, because we have all concluded the game to be a North London Derby draw tie.
Firstly the match wasn’t a north London derby. The north London derby is the game between Arsenal and Tottenham, Manchester United is a club in Manchester and plays their derby only against Manchester City. This game could be termed a Rival match because of the great rivalry or history both teams have shared in the past.
Secondly I would agree without you that Manchester United made a costly mistake this transfer window for not signing a new Center Back. But that is not a Ten Hag’s problem, because the united hierarchy were scared of FFP and only wanted to sign a new Center half only if they get to sell or loan Harry Maguire away but the Englishman didn’t want to leave and that is why they didn’t sign any CB. They rather went on to get former academy graduate Jonny Evans to sign a season contract after being released by Leicester City this summer.
The mistake made by Ten Hag in that game was substituting out Victor Lindelof who was actually having a great game along side Martinez. Evans came on and looked shaky at the back and that caused United the second goal scored by Rice.
