Chelsea midfielder Jiri Jarosik wants to sign for Birmingham permanently - if the club remain in the Premiership.
The 28-year-old is on loan at St Andrews and Chelsea boss Jose Mourinho has stated it is "unlikely" the Czech will return to Stamford Bridge.
Birmingham are third from bottom in the table and Jarosik's agent Viktor Kolar told BBC Sport: "If Birmingham stay up, we will talk to them about staying.
"We heard manager Steve Bruce wants to keep him. He wants to stay in England."
Jarosik joined Chelsea from CSKA Moscow for a reported £3m in January 2005 but made only 20 appearances for the Premiership champions.
He has been on loan at Birmingham since August and the deal includes an option for Blues boss Bruce to sign him in the summer.
"He wants to play regularly and that would be impossible here"
However, Birmingham must first stay in the top flight.
"Jiri is fully focused on keeping Birmingham in the Premiership," added Kolar.
"He is convinced they will not be relegated but if they do go down, it is unlikely he would stay."
Kolar confirmed several other English clubs had expressed an interest in signing the Czech Republic international.
However, it appears a return to Chelsea is out of the question.
"It's unlikely that Jarosik will return," said Chelsea boss Mourinho.
"He wants to play regularly and that would be impossible here."
