"I can't hide it - we have a lot of offers for Andrej," Kramaric's agent Amir Ruznic told Russian paper Izvestia.
"Many well known European clubs wants him and he really wouldn't mind if he would move to Russia.
"The Russian league has developed a lot in recent years and is right now one of the best in Europe. But it is too early to talk about all this.
"Andrej is only thinking about how to score many goals as he can until the end of the season. Then we will see what will happen."
