Well, this one came out of almost nowhere less than a month ago and one of Barcelona's star players has now moved for a new world record. It's the biggest transfer this window. This biggest transfer in history. Though Barcelona now have £198m to spend on new talent.
Lukaku was linked with a move back to Chelsea but chose Manchester United instead and is now a teammate of his friend Paul Pogba. Reports suggest the final price with add-ons could be a new world-record of £90m. Wayne Rooney went the other way in a separate deal.
Morata scored 15 goals in 26 appearances for Real Madrid in La Liga last season but wanted a chance to become undisputed first-choice. Antonio Conte gave him that chance.
Mendy impressed with Monaco last season and will now have to deal with the pressure of being the world's most expensive defender at Man City.
City have been on the lookout for full-backs and made Spurs' right-back Walker the joint-most expensive defender in history for a fee that will reach £50m with add-ons.
He almost moved to Atletico Madrid but due to their transfer ban, Lacazette arrived at Arsenal from Lyon this summer instead.
Portugal international Silva won Ligue 1 with Monaco last season and caught the eye of Pep Guardiola, who snapped him up in June before any other major clubs had done business.
A reliable, selfless performer in defensive midfield, the Serbia international reunites with his former manager at Chelsea as Man United seek to win their first Premier League title since 2012-13.
Another starlet from Monaco's Ligue 1 winning side, Bakayoko chose to line up alongside N'Golo Kante in a fearsome looking midfield at Chelsea.
It is a transfer that rocked Italy as Milan kept up their spending spree by stealing one of Juventus' best players. Instead of heading off to Chelsea, Bonucci chose to stay in Serie A.
With another €15m in add-ons to come, Bayern have secured their future with the signing of the 22-year-old midfielder.
With Joe Hart farmed out on loan and Claudio Bravo not trusted, Pep Guardiola spent a record fee for a goalkeeper on the 23-year-old Brazilian stopper. He could be No. 1.
Salah did not impress too much during his spell at Chelsea a few years back, but Liverpool will hope he can overcome his past.
The Roma defender made it clear it was Antonio Conte that persuaded him to move to the Premier League and the 24-year-old has plenty of time to develop his game.
AC Milan continued their summer of spending by adding the 21-year-old forward to their strikeforce. Big things are expected.
Atletico Madrid are under a transfer ban until January 2018 but signed the Spain winger and immediately loaned him out to Las Palmas.
The Sweden international was linked with a move to Old Trafford for almost six months and finally completed the deal in June as Jose Mourinho got his first signing of the summer.
