Milan has signed Estupiñán as their new LB by the way after parting ways with Theo Hernández. A decent signing for a cheap price like 17 million euros.

It's good to hear this news from Estupiñán. He has no place in Brighton after his former club signed De Cuyper. He was impactful player on Brighton, but performed so badly last season. He's liability in brighton, and that's the reason why they sold him to Milan.
On other hand, IMO, Milan's decision to get him for 17m looks a bit overpaid. I thought it would acceptable if they get him for 15m or less. It's because he's wildly inconsistent.
