Aguero is my all time favourite player and I feel desperately sorry for him. His career seems to be fizzling out and he does not deserve that at all.
If I put my ruthless head on, I think the club did the right thing. I'd loved to have kept him on, but - as ever - the club show unerring judgement on players. We could no longer rely on him to be fit. As good as he is, he can't play when he is injured which is most of the time now.
I hope he can play for a decent chunk of the season, but he needs to think about what his body is saying to him. I hope when he does retire, it's at the top and not after another injury ravaged season.
