10. Giacomo Raspadori

• From: Napoli
• To: Atletico Madrid
• Position: Forward
• Age: 25
• Fee: €22m (£19m)

Raspadori has ventured outside his native Italy for the first time in his career after three seasons with Napoli, where he won Serie A last season.

The versatile attacker, who began his career with Sassuolo, has agreed a five-year contract for his Spanish switch.

Atleti are paying an initial €22m for Raspadori, but the price could rise to €26m with add-ons.

9. Johnny Cardoso

• From: Real Betis
• To: Atletico Madrid
• Position: Midfielder
• Age: 23
• Fee: €24m (£20.7m)

Cardoso went from strength to strength during his 18 months at Real Betis and was a key figure in the club’s run to the 2025 Conference League final. 

Tottenham Hotspur obtained a priority option to sign the USA international as part of the deal that sent Giovani Lo Celso to Betis in 2024, but that agreement expired in June.

He will now remain in LaLiga as Atletico Madrid have paid Betis an initial €24million and another €5million in add-ons to secure his signature.

8. Renato Veiga

• From: Chelsea
• To: Villarreal
• Position: Defender
• Age: 21
• Fee: €24.5m (£21m)

Frustrated with his situation at Chelsea, Veiga left for Juventus on loan for the second half of last season.

He seemed to be on course to join Atletico Madrid earlier this summer, but in the end, Villarreal won the race for his signature.

They have paid an initial €24.5m, but the price could rise closer to €30m with add-ons.

7. Joan Garcia

• From: Espanyol
• To: Barcelona
• Position: Goalkeeper
• Age: 24
• Fee: €25m (£21.4m)

Garcia became the first player to make the cross-city switch from Espanyol to Barcelona since 1994 when his release clause was triggered in June.

After making more saves than any other goalkeeper in the 2024-25 LaLiga season, Garcia signed a six-year contract with Barcelona, who relied on Wojciech Szczesny in the absence of Marc-Andre Ter Stegen over the course of the last campaign.

“I’m ready for this challenge,” Garcia, whose only full season as a regular starter in LaLiga was the last one, said. “I know there is competition in this team, and this is normal in a big club like Barcelona, but I think it’s healthy and makes us all better.”

6. David Hancko

• From: Feyenoord
• To: Atletico Madrid
• Position: Defender
• Age: 27
• Fee: €30m (£26.2m)

Previously on the verge of a move to the Saudi Pro League, Hancko has instead stayed in Europe by signing for Atleti.

His move from Feyenoord is worth an initial €30m, but there are also add-ons attached to the deal.

Able to play as a centre-back or left-back, Hancko – who is the first Slovakian player Atleti have ever had – has signed a contract until 2030.

5. Georges Mikautadze

• From: Lyon
• To: Villarreal
• Position: Striker
• Age: 24
• Fee: €31m (£27m)

Mikautadze looked like a gettable player all summer with the chaos Lyon were initially under, but after things settled down, it took until deadline day for him to secure a move.

The Georgian striker has joined Villarreal – who sold striker Thierno Barry to Everton earlier in the window – for a fee confirmed by Lyon to be €31m.

Furthermore, there are also €5m of add-ons attached to the agreement.

4. Franco Mastantuono

• From: River Plate
• To: Real Madrid
• Position: Attacking midfielder
• Age: 17
• Fee: €45m (£39m)

Real Madrid have made their confidence clear in some of South America’s most promising teenagers before with big investments in players like Vinicius Junior and Rodrygo.

Their latest prospect isn’t a Brazilian, but an Argentine. Mastantuono has been making waves with River Plate before the age of 18 and has even earned his first senior cap for his country.

Madrid agreed a deal to welcome Mastantuono once he turns 18, paying his €45m release clause to confirm his arrival on what will be a six-year contract.

3. Alex Baena

• From: Villarreal
• To: Atletico Madrid
• Position: Attacking midfielder
• Age: 23
• Fee: €45m (£39m)

Making the first transfer of his career, Baena currently accounts for the biggest move between two LaLiga clubs this summer.

The attacking midfielder or winger was a Villarreal regular for the past three seasons on the back of helping them win the 2020-21 Europa League.

Now, Atleti have signed him on a five-year contract after paying €45m for his services. The overall cost of the transfer could reach €50m with add-ons, but even before then, Baena has become Villarreal’s record sale.

2. Alvaro Carreras

• From: Benfica
• To: Real Madrid
• Position: Left-back
• Age: 22
• Fee: €50m (£43.4m)

A Real Madrid academy graduate, Carreras moved to Manchester United’s academy in 2020 but failed to make a first-team appearance for the club and was sold to Benfica in 2024.

He went from strength to strength in Portugal and Madrid have now forked out €50m to bring the 22-year-old back to the Bernabeu.

“I left this house as a child and I came back as a man,” he said during his presentation. “I am proud to be in this team, which is the best in the world.”

1. Dean Huijsen

• From: Bournemouth
• To: Real Madrid
• Position: Centre-back
• Age: 20
• Fee: €59m (£50m)

The battle to sign Huijsen was fierce after he impressed in his debut Premier League season with Bournemouth.

Ultimately, Huijsen followed his heart and returned to the country he grew up in and represents internationally.

Madrid triggered the £50m release clause in the defender’s Bournemouth contract and put him in their squad for the Club World Cup.

“I’ve wanted to be here since day one, since they called me, I didn’t consider any other team,” Huijsen, a former Malaga academy player, said at his presentation. “I’m joining the best club in the world, and I’m here to give my all.”
