Rivaldo moves to the AFC Champions League surprise package from Greek Super League club AEK Athens.
Kuruvchi (Bunyodkor) boss Mirdjalol Kasimov told reporters that he was looking forward to working with his new Brazilian signing.
Rivaldo is set to be unveiled on September 2 after the Uzbek Independence Day holiday.
Drawn to face Iran’s Saipa in the last eight of Asia’s premier club competition, Kuruvchi (Bunyodkor) had earlier targeted Barcelona hotshot Samuel Eto’o of Cameroon only for the deal to fall through and Rivaldo’s timely arrival provides Kasimov with more options upfront.
Kuruvchi are currently leading the league on 51 points after 19 games, five points ahead of defending champions Pakhtakor who have a game in hand.
