The 10 most expensive signings in Serie A this summer

AC Milan accounted for the top two highest fees spent in Serie A this summer, but which other Italian teams invested heavily and which players for?

The transfer window closed in Italy on September 1 after Serie A clubs had been making the most of the chance to strengthen their squads. The likes of Milan, Inter, Roma and Atalanta were busy rearranging their squads after the appointments of new coaches.

You can also check out the most expensive signings in the Premier League and the most expensive signings in LaLiga, but if it’s Italian football you’re interested in, here’s where to find the biggest deals done in Serie A.

Transfers are ranked by the initial fee paid, although any ties are split by taking into account the future add-ons that could be paid.

10. Luis Henrique

  • From: Marseille
  • To: Inter Milan
  • Position: Winger
  • Age: 23
  • Fee: €23m (£19.9m)

On the back of the best season of his career with Marseille, Henrique became a target for Champions League runners-up Inter.

TEAMtalk’s Rudy Galetti confirmed Henrique was on Inter’s radar in May and the wide man has since signed a five-year contract in Milan. Add-ons could take the cost up to €25m for Inter.

Henrique made his Inter debut at the Club World Cup and has played as a right wing-back so far.

9. Ange-Yoan Bonny

  • From: Parma
  • To: Inter Milan
  • Position: Striker
  • Age: 21
  • Fee: €23m (£19.9m)

After working under new Inter coach Cristian Chivu last season with Parma, Bonny made the same move on July 5.

The initial €23m fee could rise to €25m with add-ons.

“It is a childhood dream come true for me, I am still struggling to realise what’s happening,” he told Inter TV. “I can’t wait to get started.”

8. Roberto Piccoli

  • From: Cagliari
  • To: Fiorentina
  • Position: Striker
  • Age: 24
  • Fee: €25m (£21.6m)

After making his move from Atalanta to Cagliari permanent earlier this summer, Piccoli has moved on again, which sees the Sardinians more than double their money.

Piccoli scored 10 goals in Serie A last season and will be hoping to make further progress with Fiorentina, whose deal to sign him is worth €25m with another €2m in bonuses.

7. Noa Lang

  • From: PSV Eindhoven
  • To: Napoli
  • Position: Winger
  • Age: 26
  • Fee: €25m (£21.6m)

Napoli have been bolstering their squad in the summer transfer window as they aim to retain the Serie A title in 2025/26.

Kevin De Bruyne arrived on a free transfer and they bought Luca Marianucci from Empoli for €9m but their most expensive signing is currently Lang, who has cost the club an initial €25m plus €3m in add-ons.

The Netherlands international is coming off the back of a brilliant season with PSV Eindhoven, where he registered 14 goals and 12 assists in 44 appearances in all competitions.

6. Wesley

  • From: Flamengo
  • To: Roma
  • Position: Right-back
  • Age: 21
  • Fee: €25m (£21.7m)

After featuring at the Club World Cup with Flamengo, Wesley has earned his European breakthrough by joining Roma.

There’s a heavy emphasis on the importance of wing-backs in their new coach Gasperini’s system, so the ex-Atalanta boss was eager to bring the Brazilian in for the right flank.

Wesley has cost Roma an initial €25m, a fee that could rise to €30m with add-ons, and has signed a five-year contract in the Italian capital, where he scored on his Serie A debut.

5. Nikola Krstovic

  • From: Lecce
  • To: Atalanta
  • Position: Striker
  • Age: 25
  • Fee: €25m (£21.7m)

Krstovic has climbed up Serie A to join Atalanta from Lecce in a deal worth €25m plus €5m in bonuses and a sell-on clause.

The Montenegrin striker bagged 12 goals last season for a side hovering above the relegation zone, but now has Champions League involvement on offer.

4. Nico Gonzalez

  • From: Fiorentina
  • To: Juventus
  • Position: Winger
  • Age: 27
  • Fee: €28.1m (£24.3m)

Juventus acquired Gonzalez from Serie A rivals Fiorentina last August on loan with an obligation to buy.

That obligation was dependent on certain conditions, but having been activated, the Argentina international is now permanently a Juventus player on a contract until 2029.

He only scored three league goals from 26 games in his first season with them, though, and on deadline day he was sent on loan to Atletico Madrid.

3. Sam Beukema

  • From: Bologna
  • To: Napoli
  • Position: Centre-back
  • Age: 26
  • Fee: €31m (£26.8m)

After two seasons with Bologna, Beukema has joined the reigning champions Napoli for a fee of €31m.

Last summer, Bologna sold a valuable defender in the shape of Riccardo Calafiori to Arsenal and this year it’s Beukema’s turn. Bologna have practically tripled their money on him.

The Dutchman, who is yet to win a senior cap for his country, has signed a five-year contract in Naples.

2. Ardon Jashari

  • From: Club Brugge
  • To: AC Milan
  • Position: Midfielder
  • Age: 23
  • Fee: €36m (£31.2m)

One of Milan’s top targets for the summer, the Rossoneri got their way by winning the race for Jashari.

Club Brugge accepted a bid worth an initial €36m, which could rise to €39m with add-ons. Milan have given the midfielder a contract until 2030.

According to reports in Italy, there are three separate add-ons in the deal worth €1m each: one for if Milan qualify for the Champions League in the next five years, one if they reach the semi-finals of the competition and one if they win Serie A.

However, Jashari has already suffered a serious injury barely weeks into his Milan career.

1. Christopher Nkunku

  • From: Chelsea
  • To: AC Milan
  • Position: Forward
  • Age: 27
  • Fee: €37m (£32m)

Nkunku wasn’t content with his situation at Chelsea and attracted interest from across Europe before signing a five-year deal with Milan.

The attacking midfielder or striker will be playing in Serie A for the first time in his career after Milan agreed to pay €37m, rising to €42m (£36m) for his services.

Nkunku spent two years with Chelsea and now takes on a new challenge with Milan, following in the footsteps of various other players to tread that path in recent years.
