The 'here we go' is on hold, the 'bombas' are done and dusted and the window panes are reverberating after being forcefully closed on Tuesday night.
Now comes the moment for new arrivals to make their mark on the pitch rather than the balance sheet.
Throughout the Premier League era there have been hordes of transfer hits and misses, but here we're looking at those signings who proved game-changing for their club and the competition, the ones who really moved the needle.
I've ranked my top 10 and here are my Manchester City choices and where they are placed.

It gets somewhat lost in the cloudy narrative of the past, but Robinho had a decent first season at Manchester City, scoring on his Premier League debut and netting 14 times in 31 top-flight games to finish as their top scorer.
Things went downhill from there, but Robinho's performance was less important than what his arrival meant for the future of English football. It was City laying down a marker.
On the day the club were bought by the Abu Dhabi United Group - it also happened to be transfer deadline day - they nabbed one of the world's most prominent players from under the noses of Chelsea for a British record fee.
City finished 10th that season. But 18 years and more than £3bn on transfers later, they have become the most dominant club in England, winning eight titles.

Sergio Aguero set out on his debut as he meant to go on, scoring twice and setting up another in a 30-minute cameo off the bench against Swansea City.
Manchester City were without a top-flight title since 1968 when the Argentine arrived from Atletico Madrid.
Ten months later he had netted 23 goals in 34 Premier League games, including the one deep into stoppage time that crowned City champions.
City had spent lavishly on forwards previously but the prolific Aguero was a game-changer.
His goals shifted the power balance in Manchester and, after a decade in sky blue, he departed as the club's all-time record scorer with 260 goals to complement his five league titles.
