Arsenal were next up to take on Premier League leaders Manchester City and it took them just 19 minutes to fall behind.
The Gunners started the contest rather positively but City’s attacking threat proved too much, Kevin De Bruyne opening the scoring with a fine left-footed finish.
The goal appeared to sap all the energy from Arsenal, with Alexis Sanchez and Mesut Ozil looking particularly uninterested in proceedings at the Etihad Stadium.
Sanchez, who saw a deadline day move to City fall through, drew fierce criticism from the Arsenal supporters, with Piers Morgan seeing the funny side of the Chilean’s struggles.
“Loving Sanchez today - he’s playing so badly City won’t want him in January,” the celebrity Gooner tweeted in the first half.
Indeed, the question of whether Sanchez would even get into City’s starting line-up has to be asked.
Pep Guardiola’s side have been devastating going forwards this season, De Bruyne’s goal their 36th in the league this season.
Through 11 matches, that’s simply incredible.
Sterling messed up a 2-on-1
It could have been 2-0 shortly after the goal when Raheem Sterling raced through with a two-on-one opportunity.
The England forward attempted to pass to Leroy Sane but overhit his delivery - much to the annoyance of Guardiola.
The former Bayern Munich boss threw his arms up into the air and sunk back into his seat with the frustration etched on his face.
Sterling has been immense this season but it definitely wasn’t his finest moment.
Twitter loved it
Here’s how fans on Twitter reacted to Guardiola’s show of anger.
Sterling has scored 10 goals in all competitions this season and Guardiola attributes his good form to his extra work on the training ground.
“It’s true that in front of goal it’s improving,” Guardiola said this week, per The Guardian.
“He’s enjoying scoring goals, he’s not scared, he’s not afraid to take a risk. And now he’s seeing how fun, how good it is to score goals. Now he’s more focused on that.
“Mikel Arteta [one of Guardiola’s assistant coaches] is working many hours and days after training specifically about the last action on the pitch – that control in the last moment to make the right movement in the final three or four metres.
“Raheem has wanted to stay there, to improve, to practise, to shoot at the goalkeepers. It’s part of the mentality he needs. He knows a striker has to score goals and he has to do that if he wants to achieve the next step.”
It’s no wonder, then, that Guardiola was so upset with Sterling - he knows just what he can do.
