German Bundesliga pair of Hoffenheim and Hannover 96 have both joined Russian side Lokomotiv Moscow to vie for the signature of Ghanaian goal-monger Richmond Bokaye-Yiadom.
According to reports from Serbia Red Star have already turned down the offers on the grounds of under valuation.
Red Star believe the former Juventus forward should cost more than €6 million and will not sanction a move out of the Stadion Rajko Mitić.
Boakye has hit top form since his arrival from Italy, scoring over 25 goals in one-and-half seasons.
It is believed that Hoffenheim will return with an improved bid as they have set their sights on making the former Genoa prodigy their third Ghanaian signing in recent years after Prince Tagoe and Isaac Vorsah.
