#3 Nikola Vlasic (CSKA Moscow to West Ham United) - €30 million
After it became clear that West Ham would not be able to bring back Jesse Lingard on a permanent transfer, the Hammers decided to look elsewhere for his replacement. Their search led them to sign Nikola Vlasic from CSKA Moscow for around €30 million on deadline day of the transfer window.
The 23-year-old Croatian international was a creative force for CSKA Moscow. He has made more key passes (167) than any other player in the Russian Premier League since joining the club permanently from Everton in 2019.
During his time at the club, Vlasic scored 33 goals in 108 appearances and set-up another 21 for his team-mates, helping the club compete on domestic and European fronts.
Vlasic's arrival will provide excellent competition for the likes of Said Benrahma and Pablo Fornals at the club.
#2 Cristiano Ronaldo (Juventus to Manchester United) - €45 million
The deal for Cristiano Ronaldo was announced a couple of days prior to deadline day. But Manchester United officially completed the transfer on deadline day to cap off a brilliant transfer window for the Red Devils.
Despite ending last season as the top scorer in Serie A with 29 goals and winning the Capocannoniere, Ronaldo was not entirely happy at Juventus. The Turin-based outfit were also ready to offload him as their financial conditions were dire and Ronaldo's salary was taking a big chunk out of their wage bill.
The 36-year-old was heavily linked with a move to Manchester City during the last week of the transfer window. But the Portuguese superstar sealed a comeback to Old Trafford in a deal worth €15 million, with the news creating huge excitement among United supporters.
Ronaldo scored two goals on his debut against Newcastle and since then has added a further two in three games across all competitions. United fans will be hoping that Ronaldo can carry on this form and finally bring the glory days back at Old Trafford.
#1 Eduardo Camavinga (Stade Rennes to Real Madrid) - €55 million
Eduardo Camavinga is widely regarded as one of the most exciting young prospects in world football. The Frenchman was keen to move to Real Madrid at the start of the transfer window. But with Real focused on securing a transfer for Kylian Mbappe, it looked like Camavinga would stay put at Rennes.
However, with Real Madrid frustrated in their pursuit of Mbappe, they turned their attention towards securing a deal for Camavinga. Los Blancos paid €31 million to sign the youngster on deadline day of the transfer window and bring him to Santiago Bernabeu.
Camavinga had made his professional debut for Rennes at the age of just 16 in 2018. He went on to play 88 games for the club, scoring two goals and registering five assists.
The 18-year-old also became the youngest player to be called up to the French national team at senior level since 1932 when he received a call-up from Didier Deschamps.
Camavinga started life at Real Madrid in brilliant fashion, scoring just six minutes after coming on for his debut.
For just €31 million, the midfielder already looks like one of the bargain buys of the summer transfer window.
