Bayer Leverkusen had an agreement in place for the services of Sardar Azmoun (27), who was out of contract in the summer. However, after a falling out with Zenit St. Petersburg, Azmoun now joins Seoane's squad in the winter transfer window itself. The Russian giants bid farewell to the Iranian on their Twitter handle today. Per BILD, Bayer have transferred just 2 million Euros to the Russian side to acquire Azmoun's services. "We are pleased with the constructive agreement with Zenit and that we can now rely on Sardar's qualities at an early stage. He will enrich our offensive game and significantly enhance our very good squad once again," said Simon Rolfes, Sporting Director of the club.
