The former Gers skipper believes that the Hoops reappointing their old boss would be a good move.
Barry Ferguson believes that the impact that Walter Smith had during his second spell with their Old Firm rivals Rangers should persuade Celtic to go out and reappoint Neil Lennon as their next manager, the Daily Record reports.
The Scottish Premiership side are looking for their new boss after Ronny Deila announced that he will be leaving Parkhead at the end of the season.
And having been part of the Ibrox dressing room when Paul Le Guen's unsuccessful tenure came to an end, and witnessing how the return of a manager who understood the club dragged them out of the gloom, he suggested that, while Deila does not deserve to be put in the same category as the Frenchman having enjoyed some success with the side, Lennon can have a similar impact by returning to the Hoops.
"In just 90 minutes, Walter Smith had made Rangers Rangers again," he told the Record.
"And that's why I see a very simple answer to the riddle of who Celtic should chose to replace Ronny. Forget Deila being the new Le Guen, as far as I can see, Neil Lennon can be Celtic's Walter Smith.
"He was at Hampden on Sunday and he saw with his own eyes that Rangers are ready to come after Celtic," he added.
"Can you imagine how he would have reacted if that was his team coming into the dressing room at half time? They would have been too scared to walk in through that door because Lennon simply would not have accepted a performance as woeful as they had just given. He'd have torn the paint off the walls because, unlike Ronny, he knows what this rivalry is really all about."
In his second spell - which lasted just over four years - Smith won three consecutive league titles, two Scottish Cups and three League Cups to help the side banish the painful memories from Le Guen's poor spell as head coach.
Though Lennon would have much less work to do to keep the Bhoys at the summit, his understanding of the club will surely help him have the immediate impact that Smith had, which could be invaluable given that their bitter rivals will be back in the top flight next season, and will have plenty of confidence following their Scottish Cup semi-final victory.
