“There is definite interest there from Everton,” Callaghan told Ireland’s Evening Herald newspaper.

“It’s just a matter of what they do with it, but they are keen on Kevin.

“[Everton] are not the only ones interested. Charlton had Kevin over for four days and while he didn’t play in a match when he was there he impressed in training and they’d like to have a second look.

“I would hate to lose Kevin but if we were able to sell him and bring in some finance for the club it would be positive all round as he really wants to further his career.”
