Lokomotiv Moscow have warned Stoke City of delays over their loan signing of winger Haminu Dramani.
Stoke confirmed earlier this week that they had a agreed a season-long deal for the 22-year-old with a view to a permanent deal.
A work permit was all Stoke appeared to be waiting for, but now Lokomotiv have said that they will not be letting Dramani leave until the end of November - when the Russian season ends.
"Dramani remains with Lokomotiv until the end of the season," stated Lokomotiv president Nikolay Naumov.
