I still think we need another defender, especially given we have 3 players in that area (De Vrij, Acerbi, Darmian) which we may need to replace within the next 2 years. If we're not spending the money on a striker, I'd use it on a defender.If we get Augusto, we can skip another defender. Augusto could be a back up to Bastoni as well, so Bisseck will be Darmian cover. We need third forward more urgently.
I assume we're still onto Tiago Djalo if he recovers well from his ACL injury for a free transfer next season.
