Celtic have made an approach to Chelsea about midfielder Jiri Jarosik, but the Czech's agent has warned that he is more likely to move to Russia.
Jiri Jarosik has been on loan with Birmingham
The 28-year-old, who has been on loan with Birmingham, will decide where his future lies in the next few weeks.
Agent Victor Kolar told the Daily Mail: "I have recently had discussions in Prague with Celtic over Jarosik.
"But there is strong competition for the player from Russia and more than one English club interested."
Jarosik joined Chelsea from CSKA Moscow in January 2005 but has made just 20 appearances for the English champions, only six of them starts.
But he made 32 appearances during a season-long loan to relegated Birmingham, who were hoping to sign him permanently.
"There are also offers from Germany and Spain," added Kolar.
"Jiri is just sitting back now, deciding his future, so we have not given anyone an answer.
"But he thinks it might be better to return to Russia, where he knows the language, or maybe stay in England."
