I think you're misremembering things.
As frustrating as he was at time, he did far, far more good than bad here.
There's a reason he had thousands and thousands of people chanting his name and trying to convince him to stay during his last title parade and it certainly wasn't nostalgia.
No I agree that he was much loved, very good for his age and looked good going forward a lot of the time.
He also had frustrating games where he was sulky and wasn’t effective, which was to be expected from such a young talent, and looking at his trajectory it seemed that he was destined to become a stand out for his generation.
My point is that he didn’t kick on, he kept his blowing hot & cold flaws, he didn’t build on his talents, he never reached anything like the heights we hoped for and expected.
Now he’s a 27 year old with the same flaws he had when with us and maybe a few new one’s.
He played 90 games for us and scored 25 goals O.28 goals a game, in his 90 games for Bayern he’s scored 20 goals 0.22 goals a game. In an easier league he’s now scoring less and it’s plain to see that his effectiveness has not just stalled, it’s gone backwards.
If he’d ever reached his promise then yes, I’d have wanted the sulky speedster back but he hasn’t and now, at his age, won’t.
I’m not misremembering anything mate, I’m remembering what was, what we hoped for and what actually came about. What came about isn’t what we wished for and if you think it through then I recon you’ll come to that conclusion.
PS. I also loved Balotelli but he didn’t build on his very obvious talent and I wouldn’t want him back either.
