He told Absolute Radio: "There’s talk about Ashley Williams leaving. Liverpool, Arsenal, I think they’ve been heavily linked with Ashley Williams, our captain, captain of Wales, who’s really, really come on and he’s been a top player for the last two or three years.
"He looks very comfortable now in that position, 28 years of age and in the prime of his career. But who knows in the summer Wrighty, if Williams stays or go. Michu, if someone comes in with 50 million for Michu, it’s a no brainer, they paid two for him, they’d have to sell him, there’s talk about the manager."
