Dear Fabio.
If anything, please make this team faster and more athletic for next season. Ajax exposed our biggest weakness, and they used it to their advantage by getting into their comfortable pockets on the pitch with little resistance. Our players couldn't keep up. While their players may not be on the same technical level as ours, they were able to get where they needed to be with relative ease, thereby causing so many problems.
If it means selling Pjanic, Dybala, Mandzukic, Bonucci, et al.... so be it.
