Hearts boss Jim Jefferies reckons Alexei Eremenko will leave Kilmarnock for England in the summer.
West Bromwich Albion have been watching the Finland playmaker.
Jefferies said: "Eremenko has not just been good for the SPL and Kilmarnock, he's been good for the players around him.
"Just look at what happened to Conor Sammon.
"Conor is good at playing on the shoulder and making runs and with Eremenko's passing it was an explosive mix.
"Conor went on to score the goals that won him a terrific move to the English Premier League but you could put a high percentage of his goals down to Eremenko. That's how good he is.
"They all rave about his qualities and rightly so. He could play absolutely anywhere."
