He's already bagged his first goal and added an assist in Atletico's three victorious matches of the 2019/20 season.

Antoine Griezmann — $129.8M — Atletico Madrid to Barcelona

The Frenchman Antoine Griezmann turned heads when he announced his intention to sign for Barcelona, the club he ditched just a year before to remain at Atletico Madrid. The $129.8M transfer fee paid by the Blaugrana was the summer's second-largest deal after Joao Felix. The forward has enjoyed a strong start to the Catalan giant's campaign, scoring two goals at Camp Nou and providing one assist so far three games into the season.

Harry Maguire — $96.5M — Leicester City to Manchester United

The England international Harry Maguire became the most expensive defender ever in signing for Manchester United this summer. The $96.5M transfer fee edged out Virgil Van Dyk's record-setting fee for a defender last year. The 6'4 foot Maguire who calls ‘the Beast' looks to strengthen a Red Devils defense alongside Wan-Bisakka, Lindelof, and Luke Shaw.

 

Nicolas Pepe — $86.8M — Lille to Arsenal

Arsenal made 24-year-old Ivory Coast winger Nicolas Pepe the club's fourth signing this summer, shelling out a club-record $86.8 million to snag the player from French side Lille.

Romelu Lukaku — $84.4M — Manchester United to Iner Milan

After a summer spent pushing for an exit from Manchester United, Romelu Lukaku finally found his calling on deadline day in Inter Milan.

Lucas Hernandez — $82M — Atletico Madrid to Bayern Munich

Matthijs De Ligt — $81.8M — Ajax to Juventus

After a summer vacillating between Manchester United, Barcelona, PSG, and Juventus, Matthijs De Ligt selected to join the Turin side. There is no doubt the legendary Cristiano Ronaldo helped influence the Dutch defender's decision. Given the extended injury to Juve starting center-back Giorgio Chiellini, Matthijs de Ligt should get plenty of game time to shine for the Bianconeri.

— $78.8M — Ajax to Barcelona

While the Dutch midfielder expected to play for Arsenal before Barcelona in taking the “Marc Overmars route,” Frenkie went straight to Camp Nou. The 22-year-old starred in last year's Champions League tournament and helped Ajax their first trophy in five years, along with the Eredivisie title.

Spanish defensive-midfielder Rodrigo signed to Manchester City for a whopping fee of $75.5 million. The 23-year-old is already a Pep Guardiola favorite, an excellent passer who can hold possession of the ball and build from the back.
