Chelsea have been involved with Sterling for a long time and will do their best to include him in the team. But we'll see if it's worth paying such a high price.
I do not consider what it's rumored chelsea are willing to pay for Sterling as a high price (around £50m), Sterling has been magnificent for City since joining the club, he is also a complete professional who doesn't complain or bring disunity in the dressing room when he isn't playing regularly. If you look at the amount of money that clubs have been spending on players lately, then you definitely can't call this a high fee, Spurs signed Richarlison who is not an established footballer for around £60m, and Arsenal signed Gabriel Jesus for £45m, it is what it is, and Raheem Sterling is just 27 years old, he still has quite a lot of years ahead of him, so if Chelsea get him now for that price, it is a worthy bargain.
Having said that, the problem here is for City, and that's not because they are letting Sterling go, but they are selling him to their direct rival Chelsea, i just hope this does not affect them in the grand scheme of things come the end of next season.
