The 23-year-old, who excelled with Setif in the past couple of seasons, penned a four-year-deal with Sion as he was unveiled on Monday.

The announcement follows a dispute between Zamalek and Sion for the services of the highly-rated Ivorian.

Zamalek chairman Mamdouh Abbas claimed recently that Die is set to join the club, but the player snubbed the Whites for Sion.

Earlier this year, Sion were involved in a dispute with Ahli over the controversial transfer of Essam Al-Hadari, who eventually joined the Swiss Super League side.
