Which average are we talking about? He's way above Premier average since coming back from injury a couple of seasons ago.
A very very good record last season and this. 25 last year, scoring against Liverpool, Leicester, Spurs, Arsenal. The video is a good watch. There are a lot of goals of the type we laud Aguero for. Precision finishes from the edge of the box, and a tonne of good finishes all round in fact, plus some real poacher's moments including two where he's literally mugged the keeper. That would fit in very well with our game.
This season, Southampton went into freefall at the start of 2021, and I wouldn't pay too much attention to him not scoring when they are losing 9-0, all in all shipped 34 goals in 12 games, three of which he wasn't available for. He's still 9 in 23 which is hardly a disaster. Very comparable to Jesus's figure of 8 in 21.
All in all, as today showed, he definitely has something we lack. His scoring record is the same against big teams as the minnows - not a flat track bully. He's a very skilled and decisive finisher in his prime.
If it was him for a season and whilst we wait for Mbappe, for instance, I'd be all over it.
