The time has now come for him to re-introduce himself to some former team mates. The cauldron that awaits him at Anfield will have to wait for a good few months yet, but City's number seven will be one of the chief players looking to put Liverpool to the sword when they visit the Etihad Stadium on Saturday evening.
When people say "ooh £50million for Raheem Sterling, that's an awful lot", they're wrong. Nobody is denying that on the scale of things £50million is a substantial amount of money, but to men who command oil empires around the world and probably employ butlers to roll them the finest tobacco in $100 notes, it's just about the square root of diddly squat.
There are sub-plots aplenty in the Premier League's upcoming season. Will Harry Kane repeat his incredible performance from last season? Will Chelsea be the first team to retain the title since Manchester United in 2009? Will Tim Sherwood's head fall off under the weight of his concentrated smugness? Putting those aside for a second, let's have a look at the youngsters.
The Premier League summer transfer window is now in full swing, with all 20 clubs having conducted at least some business. High profile moves like Raheem Sterling's record transfer to Manchester City may have dominated the headlines, but what about some of the deals that just seem to make incredible sense?
What exactly is his crime? Turning down a lucrative contract offer because he wasn't happy with his general situation at the club? Not being quite as guarded with his media comments as he should've been? He's 20 years old. Show me a 20-year-old who hasn't said something ill-advised when frustrated and I'll show you a liar.
At national level, if you are high up the greasy pole, you are always on duty, always making decisions, always at the beck and call of constituents, MPs, and especially the 24 hour media. Yet sometimes you know you are jaded and only operating at half speed. What you really need is a weeks' break - or longer.
While not a carbon copy of Mourinho's 4-1-2-1-2, Manchester United, West Ham United, Queens Park Rangers and Liverpool have all, at one point or another deployed a diamond midfield in the 2014/15 campaign. The 4-3-1-2 allows teams to maintain numbers in the middle of the park, but means managers can field a creator in between the midfield and attack.
In case you've been living under a rock for the last few days, a bit of background first. England played San Marino on Thursday night, a game that Sterling started before being taken off at half time. England then played Estonia on Sunday evening and Roy Hodgson let slip that the Liverpool youngster wouldn't be starting as he'd told the manager that he felt "tired".
Liverpool haven't been handed the easiest return with a group featuring last season's champions Real Madrid, Swiss Super League winners FC Basel and new boys Ludogorets. It's a group they can realistically get out of though and will hope the fear factor of their historic European standing will unnerve the latter of those two, especially for home matches.
