Hearts of Oak are demanding US$ 450,000 from United Arab Emirates Al Nasr for the services of striker Mahatma Otoo.
The Dubai-based Etisalat Pro League side are offering US$ 300,000 for the former Ghana Under-20 skipper.
The issue will be discussed at the club's board meeting on Thursday to decide whether he will be released or not.
"Their (Al Nasr) offer is not bad but we can't let go of Mahatma because he is one of the proven stars we will be counting on to win the Glo League next season so whoever wants him must be prepared to pay more for his services," a source said.
Otoo was recently appointed captain of Hearts of Oak for the 2012/2013 season.
