Osman Bukari's market value has skyrocketed since his arrival at Red Star Belgrade.
The Serbian giants snapped up the winger from KAA Gent in the summer transfer window, and he has since scored seven goals in 13 appearances.
Three of those efforts came in the Champions League qualifiers, with his value jumping from 3 to 5 million euros and a new personal best.
In the Serbian league ranking, only teammate Mirko Ivanic is ahead of Bukari with an unchanged EUR 8 million.
Meanwhile, Red Star continues to have the most valuable squad at €54.75m – well ahead of Partizan. The city neighbour is valued at 36.74 million euros.
Bukari has been included in Ghana's squad for the pre-2022 World Cup friendlies against Brazil and Nicaragua.
