I'm sorry James, it's not 'absolute rubbish' it's simply an opinion that you don't concur with.
As it happens, I've read a lot of your posts, even going back years before I signed up to this forum. I like a lot of what you write and I keep an eye out for your moniker because I mostly agree with your opinion.
In this case, I do (obviously) agree that a match-fit Aguero has caused the dippers much grief in previous seasons.
However, IMO this will be a high energy game where we need our 10 outfield players to push hard from the off, and to press the bejezus out of them for 90+ minutes if we're to get anything out of the game.
Unfortunately, that's not what Kun's about nowadays, and he wasn't ever entirely comfortable with pressing like a maniac even when he was younger and in his absolute pomp.
Thus, my opinion remains that Jesus would always be the better choice for this particular game, for the reasons set out.
And I think the world of Aguero. I think he's the best striker we've ever had for sure, but I've watched him for long enough to know that if he were to be suddenly announced fit to play, then it would be almost pointless playing him because he's never the Aguero we want in the first 2 or 3 games after returning from an injury layoff.
PS. Having said all that, I'd be chuffed to see him coming off the bench on 60 mins, when the heats gone out of the game and he could test himself against tired legs. But not from the off. IMO
