Ghana striker Asamoah Gyan has joined Lokomotiv Moscow in the biggest purchase of the Russian pre-season. The 21-year-old moves from Italian Serie A side Udinese in a deal worth US$10.5m. Ghana international spent the last two seasons on loan at Serie B club Modena before rejoining Udinese at the start of this season. He played for his country at the World Cup in Germany in June and scored in the Black Stars' thrilling 2-0 victory over the Czech Republic. The transfer fee reflects the demand for a player who has scored 12 goals in 19 appearances for his country. But Spartak Moscow's acquisition of Argentinean Fernando Cavenaghi for US$13m in 2004 remains a Russian record. Gyan moved to Udinese from the local side Liberty Professionals in 2003. BBC
