West Brom boss Tony Mowbray believes on-loan Roman Bednar would be a snip at £2.5million.
Mowbray said: "I am not surprised how well he has played for me here at Albion. He was injured when he was at Hearts and someone told me at the time they had 72 players. I think their wage bill needed addressing.
"When we did the deal we knew he would have to be pretty good for us to pay £2.5m, but Roman has done exceptionally well.
"He has got himself fit and wants to progress and hopefully we can facilitate that here as he enjoys being with West Brom. Hopefully it will be money well spent."
