With the window in Italy having slammed shut ahead of the new top-flight campaign, Goal looks at the new faces from whom big things are expected

Cristiano Ronaldo | Real Madrid to Juventus
Five-time Ballon d'Or winner, five time Champions League winner and a domestic title winner in England and Spain, perhaps the world's finest marksman decided now was the time for him to leave Santiago Bernabeu behind and try his hand at winning the Scudetto.
Ronaldo's move for around €100 million (£88m/$117m) sent shockwaves through the footballing world and he looks set to be the star attraction wherever he goes in Italy once the season gets under way.

Radja Nainggolan | Roma to Inter
Having been surprisingly left out of Belgium's World Cup squad, Nainggolan wasted no time in plotting his next career move as he swapped Stadio Olimpico for San Siro in a deal worth an initial €38m (£33.5m/$44m).
Having worked with Inter boss Luciano Spalletti at Roma he should need little time to settle in as he looks to bring some steel to the Nerazzurri's midfield.

Joao Cancelo | Valencia to Juventus
With the full-back having impressed during a loan spell with Inter during the 2017-18 campaign, the Serie A champions decided Cancelo was the man to act as Stephan Lichtsteiner's long-term successor in Turin.
Though €40m (£35m/$46m) may seem a lot for a 24-year-old defender who has been capped just seven times by Portugal, the Bianconeri see a lot of potential in Cancelo and expect him to flourish alongside even better players.

Tiemoue Bakayoko | Chelsea to AC Milan
After a horror debut season in west London and with both Jorginho and Mateo Kovacic added to the Chelsea squad, Bakayoko is in need of a fresh start with the Rossoneri.
Though he has initially signed on loan, the France international has the option to make the move permanent if Milan are willing to fork out €35m (£31m/$40m) at the end of the campaign.

Stefan De Vrij | Lazio to Inter
De Vrij arrives at San Siro under something of a cloud after his poor performance on the final day of last season allowed Spalletti's side to pip his then employers, Lazio, to a place in the Champions League for 2018-19.
Many questioned whether he should have been playing given an agreement for him to swap Rome for Milan on a free transfer had been agreed for some time, but he will hope to put that behind him quickly at his new club.

Gonzalo Higuain | Juventus to AC Milan
Having fallen down the pecking order at the Allianz Stadium following the arrival of Ronaldo, the Argentina international knew his number was up and rejected overtures from Chelsea to sign for Milan.
Higuain initially arrives at San Siro in a loan deal, though should his move be made permanent at the end of the season the total cost for his transfer will reach €54m (£48m/$63m).

Justin Kluivert | Ajax to Roma
One of the brightest young talents in Europe, plenty are keen to see how Kluivert does having made his move to one of Europe's top five leagues.
Still just 19, the son of former Barcelona hotshot Patrick should be allowed time to settle in the Italian capital despite the Giallorossi paying an initial fee of €17.25m (£15m/$20m).

Leonardo Bonucci | AC Milan to Juventus
Having only moved to San Siro last summer, Bonucci is back with the Bianconeri and keen to reinstate himself as one of the world's top centre-backs.
He is likely to yet again partner Giorgio Chiellini at the back, though with Gianluigi Buffon no longer there as an insurance policy behind them the experienced duo will need to be at the top of their game throughout the campaign.

Keita Balde Diao | Monaco to Inter
Just 12 months on from leaving Lazio and Serie A behind, Keita Balde is back having agreed an initial loan move to San Siro.
Should the deal be made permanent, Inter will eventually have to fork out €48m (£43m/$54.7m) for the Senegal international who scored eight goals in Ligue 1 last season.

Mattia Caldara | Juventus to AC Milan
Seen by many as the brightest defensive talent in Italian football, Milan seem to have pulled off something of a coup in bringing Caldara to San Siro.
Used as part of a direct swap deal that saw Bonucci move in the opposite direction, Caldara leaves having never played a game for Juve but having done his reputation no harm with a string of impressive performances while on loan at Atalanta.

Sime Vrsaljko | Atletico Madrid to Inter
One of the stars of Croatia's run to their first World Cup final, full-back Vrsaljko is back in Serie A two years on from leaving Sassuolo for Atletico Madrid.
With an option to make the defender's loan move permanent, Vrsaljko could end up costing €25m (£22m/$29m) having been brought in as a direct replacement for Cancelo.

Javier Pastore | Paris Saint-Germain to Roma
Heralded as one of PSG's first signings under the ownership of the Qatar Sports Group in 2011, Pastore has gradually fallen down the pecking order at Parc de Princes amid the Parisiens' pursuit of European glory.
At just 29, though, he still has plenty to offer at the highest level and returns to Italy in a bid to regain his place in Argentina's squad ahead of this summer's Copa America.

Emre Can | Liverpool to Juventus
Juve continued their fine tradition of bringing in what looks, at least on the surface, yet another free agent in the shape of Germany international Can.
Injuries somewhat spoiled his final season at Anfield but the 24-year-old has time on his side and will be eager to impress following the departure of Claudio Marchisio.

Steven Nzonzi | Sevilla to Roma
Linked with Arsenal throughout the transfer window, Roma left it relatively late to bring the World Cup-winning midfielder to Stadio Olimpico for a reported fee of €30m (£27m/$34m).
The France internaitional reunites with Monchi having worked with the Giallorossi sporting director at Sevilla and will act as a replacement for Nainggolan in the Roma midfield.

Lautaro Martinez | Racing Club to Inter
One of if not the most exciting talent coming out of Argentina right now, Lautaro has the potential to be one of the new stars of Serie A during the upcoming campaign.
Eighteen goals in 27 appearances across all competitions for Racing last season saw him earn his first international cap for the Albiceleste and he has been brought to San Siro in a bid to ease the goalscoring burden on compatriot Mauro Icardi.
