Cas may go for a cash plus player deal.
Mentioned elsewhere that Roberts could go to Cas along with Mellor on a season's long loan. It appears that Cas want players to bolster their squad.
If Mellor is being touted as a loanee then we'd deduce that Deacs will be going one more year. If injury occurs then Powell could step in.
The other risk is a new visa. He may not get another due to his off field problems down under. A cash deal with 50% up front and the further amount on getting a new visa would make sense.
Good deal for Roberts as this is his last season and I don't see where he will play. He aint going to full back and Charnley will now be in front of him for the 2 shirt. A 2 + 1 deal at Cas may suit Amos.
Great these rumours, you can build a case for and against them all.
