Honestly, no. Partly because of what I think of his actual performance level, but also partly of what I continue to believe his performance level can rise to. I tend to be one of those who continues to hold out for players coming good (unless that player's name is Claudio Bravo) and I've seen plenty enough to make me believe that if MCFC keep hold of Sterling for another 3 or 4 years then he will ultimately be considered a wise investment and worth the fee.
That said, while I'm excited for Sanchez' quality in general, I also am slightly apprehensive of the transfer in general as I feel that City's attack is stocked enough right now. Aguero has for several years now been my favourite player at the club, for attitude off the pitch as much as performances on it, and I don't want to face up to any situation which sees him get squeezed out. I'd like to see him continue to score 30 goals a season and end up challenging some of the PL's biggest names on the all-time top-scorer list. If Sanchez coming in means Aguero ends up going out then it's going to take me a considerable while to get over it and put the bad blood behind me.
