Wigan Athletic midfielder Maloney said: "The value is just a reflection of the way the game is in the Premiership.
"You see players going between English clubs for big sums so it wouldn't be a surprise.
"I don't think any club who are interested will get him at a reduced price just because he's dropped to the Championship.

"But certainly in terms of the teams being linked with him, I don't think there's a great gulf between David and the keepers they already have."
