Paolo Condò who is one of the most important journalists at the Gazzetta dello Sport has written about why Mancini has chosen Sylvinho as his assistant manager:
“Mancini wanted an assistant coach who could bring and teach him something new, not someone who would just copy what Mancini already has. Sylvinho will give Mancini a bit of Wenger, Rijkaard and Guardiola.”

Hahah fair point about Wenger, Rijkaard and Guardiola, Sylvinho has more experience at the top level than pretty much anyone else currently at Inter except Zanetti and Figo 😀
Great choice for assistant coach. Sylvinho’s always been class.
This is a strong sign that mancini is staying next season.
