Speaking on the Celtic Huddle Podcast, Wilson said: "A name that hasn’t went away from the summer that I think Celtic should go for again, just to get in the door as number one and it would sort out their problem – I think they should go for David Marshall.
“People will say ‘it’s a step backwards, he’s 35 or 36 years old’. But I look across the city and see Allan McGregor coming to Rangers. Was he 38 when he came? 37? I see pictures of him holding the Player of the Year for Scotland trophy.
“I know he’s still got another year to go, but surely Marsh would be up for coming back to Glasgow.”
There's no doubt that this could be a move that makes sense for Celtic.
Moving to Parkhead would be hugely appealing for the Glasgow-born goalkeeper, and that's why a move could make sense.
Of course Derby County won't want to lose Marshall after his performances this term but with plenty of changes expected at Pride Park I wouldn't rule out a move.
