"Obinna has signed a four-year contract with Locomotiv and he has passed his medical in Moscow," his representative in Nigeria Tony Adele said.

The 24-year-old striker has moved to Russia as a free player after Inter Milan did not activate a clause on his contract that would have kept him at the San Siro.

No fee was disclosed, but it is widely believed to have matched an offer tabled by Turkish giants Galatasaray, who were willing to pay Obinna two million euros a year.

Compatriot Osaze Odemwingie left Locomotiv last year under a cloud of controversy following a racist attack by fans of the Moscow club.

Obinna returned to Italy from holidays in his native Nigeria late last week to take a decision on his club future after he played this past season on loan from Inter to West Ham, who were demoted from the English Premier League.

He was also on loan to Malaga in Spain two seasons ago.
