To be fair, Stirling has dropped off a lot the last few seasons. I don't think City got rid of him thinking he would sustain his levels or improve.Its not fantasy football were you just pick a group of 'ballerz' . Why not if they fit a system and work well with other players in that system (Sterling & Kane are excellent together, a bit like how Son & Kane worked well together). No one in that squad can do that, no one can get close enough to Kane when the ball goes into him and no one accelerates into the tight spaces in the penalty area when a ball comes in like Sterling can
Not sure he'd be the saviour you suggest here.
