It was interesting early on, he played much deeper, often finding himself in midfield at times. He served as more of a link up player and a defence mover rather than a classical forward. Similar to what we've seen from Jesus and the false 9s this season. We're becoming increasingly less direct than ever, and I feel having a conventional forward sometimes doesn't suit a slow system like that. So we may have to get used to seeing Aguero in a way we're not used to seeing him.
Weirdly enough, I thought that's when he looked at his best. It reminded me of pre-car crash 17/18 Aguero when he peaked (in my opinion). I was very impressed for 20-25 minutes or so and it's promising to think how he'll improve with games. Plus he'll always be the sharpshooter he always was.
The concern today was mainly in the form of his pressing and defensive work. The way we play, everyone and everything really needs to operate as a unit rather than a collection of individuals. He wasn't bad per se, but it's important to not be below a certain level. I will say I don't think he benefited with the teammates he had on this front. Other players pressed and covered fairly well (although not Bernardo, Foden, Jesus levels) but a larger issue was that we kept giving the ball away, so it meant he had to do more defensive work than he would have done in other games, which made the problem LOOK worse. He's only just come back so I'll give him time before I cast judgement on him, but he will need to work towards improving on this front (which there's no reason why he can't).
My favourite thing about Aguero has been that whenever he's looked like he's not a starter anymore, he works harder than ever, improves in some fashion, and gets back into the team on merit. If the trend continues he could have a great close to the season.
