Sardar Azmoun has joined Zenit from Rubin Kazan for a reported fee of €12million.
The forward, who rejoined Rubin for a second spell in 2017, has signed a three-and-a-half-year deal.
Known as the Iranian Messi by some fans in his native Iran, Azmoun had been heavily linked with a move to Premier League side Wolves in January.
Nuno Espirito Santo s side had reportedly agreed to sign him on loan from Rubin, but the move fell through when Wolves refused to allow a compulsory purchase option included in the deal.
Azmoun, who helped Iran to the semi-finals of the Asian Cup, was Zenit s second signing to be announced on Friday after they also confirmed the arrival of Wilmar Barrios from Boca Juniors.
Welcome to Saint Petersburg, Sardar!
