Ukraine striker Marko Devic is under pressure to snub Birmingham's advances and hold out for a Bosman free transfer to Dynamo Kiev.
The 27-year-old is Metalist Kharkiv's top scorer with 11 goals in 20 games this season as his side put pressure on underachieving Dynamo for a place in the Champions League.
Devic's exploits have caught the eye of Birmingham, among other European sides, as Alex McLeish looks to improve a return of just 17 goals in 17 Barclays Premier League games this season.
Metalist have offered him an extension to the contract that runs down in June, but Dynamo are willing to double his wages to £16,000 a week if he holds out to the end of the season.
Devic was born in Belgrade but took Ukrainian citizenship in 2008 and has recently become a regular in his adopted national side.
