Roy Keane and Nicky Butt would bring back the "fighting mentality" to Celtic, claims pundit Noel Whelan.
Keane has been linked with a return to management in Glasgow while former Manchester United teammate Butt leaving his Old Trafford coaching role earlier this week.
Irishman Keane has been consistently linked with the Parkhead hot seat and Butt is now being touted as assistant boss after departing the Premier League side for a “new professional challenge".
Former Aberdeen striker Whelan reckons the combination of the two would lift the Parkhead dressing room after a slump after a disastrous season.
He told Football Insider: "You keep people close to you that you’ve worked with.
"They know each other very, very well.
“Two very feisty, committed players when they were out there, but also two players who were winners, serial winners.
“That’s what they want to bring back at Celtic. They want to bring that fighting mentality back and that winning mentality because it seems like it dipped this year. It wasn’t there.
“You need to jump back onto that as quickly as possible.
"You can’t look any further than two players that have gone out and won pretty much everything, bar the World Cup.”
