Unfortunately, Atalanta doesn't think like a top team like Inter Milan or Juventus. They like prestige but are in deep debt. Atalanta, on the other hand, aims to make capital gains from the sales of their players, and in recent years they've made a lot of capital gains and still managed to win a trophy, the Europa League.
I was also surprised when I heard the news a few days ago that Mateo Retegui had moved to Saudi Arabia from Atletico. He was a player who had been a key figure at the club. After failing to join Arsenal, he finally chose to join Al-Qadsiah for €67m fee. Indeed, with the transfer fee, it is above his current market value of €45.00m.
