Former Valerenga goalkeeper Kristoffer Klaesson has been a long-term target for Leeds United.
Klaesson moved to Leeds over the summer.
Speaking on The Phil Hay Show, Phil Hay said: “The scouting departments thought a lot of Klaesson. They were in touch about him a couple of years before they actually signed him, and as soon as Casilla went to Elche, he was the goalkeeper they went after.
“They paid around about £1.5m for him, they think of him as a really, really big prospect, much as they did about Meslier when he came over from Lorient."
