The lose happen to Manchester City by mistake and no one should be blame for a single mistake after having a successful season which they won the Premier League title after a tough encounter between them and Arsenal.
Things like this do happen for team as it has also happened to Leverkusen which has won the Bundesliga title without defeat and end up losing to Atalanta that couldn't even make top four in the Italian Seria A.
Manchester City will surely have another better season in the next coming season if they did not sign a single player because there players are world class and are i good condition to compete in all competition and in any league.
That wasn't no mistake, Pep Guardiola said he knew he was tactically poor that day against Manchester United evens if they played better than Manchester United. Just that Erik Ten Hag was also brilliant made good used if his midfielder's to stop them central midfielder's ( Rodri and Kovacic ) from taking good control of the game. Manchester United players worked for the win, say it as it's meant to be.
Atalanta was incredible during that game, they man marked this players in Bayern Leverkusen man to man and didn't allow them operate easily in midfied.
Lol... For your information, Atalanta qualified for the Champions League Competition and I think they are also having one more game to play in the Seria A Competition and still leading Bologna with one point. Even with the one game to play they still occupy fourth position. Another spammer? Lol.
They will not win the Premier League Competition next season, it's all for Arsenal to step up and win it now. They have all it takes to win it.
