TBH although I like Sterling a lot, he does frustrate because he can do a lot more than what he does. For his type, a fast forward he is in his peak years. His problem is mental. he does not realise how good he could be.Mate on one hand you say his positional play is really top notch or staggering as you called it and then you are ok with city letting him go aswell. Apart from the goals and assist he conjured up last season you shouldn't forget he is only 22. Players don't reach their full potential by that age, do they? he can be a little frustrating at times but that's what you would get with young players from time to time, to let him go would be a daft move at best. He has already won us 4 points this season and that is in 3 games only
Can Sanchez deliver a 20 plus goal season though? Basic speed going and I see him more as a driving midfielder than an out and out forward. he isn't quick enough to play on the wing.
