Vagner Love is leaving CSKA Moscow for Shandong Luneng, the Russian club have revealed in a surprise announcement.
"The decision was really difficult both for the club and for the player," CSKA said in a statement. "However, Vagner received an unprecedented offer of a personal contract while CSKA received a very lucrative offer from the Chinese side."
Though the value of the transfer was not officially disclosed, sources close to the Moscow club said CSKA will receive €12m for the 29-year-old Brazilian striker.
Vagner has played 255 matches and scored 124 goals for CSKA from 2004 to '13, winning three league titles, six Russian Cups and a UEFA Cup in the process.
The departure has taken the Russian football world by surprise after Vagner in January signed a new deal with CSKA following a year with Flamengo in Brazil.
The move is also a huge blow for the team right at the start of the Russian season as coach Leonid Slutsky seeks to defend the title against a tough challenge from Zenit and Spartak Moscow.
"We would like to thank Vagner for his contribution in the club's successful display last season," said CSKA. "Thank you, Vagner, for your help in CSKA's win of three titles after your return to the club in January."
