Celtic legend Neil Lennon has hinted to Belfast Live that he regrets his decision to resign as Hoops boss back in 2014.
The 44-year-old posted his resignation after a trophy-laden four-year spell in the Bhoys' dugout, having also won plenty of honours during his distinguished playing career at Parkhead.
As a manager, Lennon led them to Scottish Premiership titles every year from 2012 until 2014, as well as bagging two Scottish Cup crowns.
Lennon, who was sacked by Bolton Wanderers last week, also inspired his troops to a shock 2-1 win over Barcelona in the 2012-13 edition of the Champions League, and the Northern Irishman admits to questioning his decision to walk away from it all.
“By 2014 I’d had a taste of the Champions League and I wanted it again and again," he told Belfast Live. “I played in the Champions League and managed in the competition and I couldn’t see it happening in the near future back then.
“It had been four years. I thought that it was a good time to take a break. In hindsight you are thinking ‘was that the right thing to do?’ At the time I thought it was the right thing to do for my family and myself."
He has, however, been linked with a return as Ronny Deila appears to be struggling for progress at Celtic Park.
The Bhoys have been eliminated from Champions League qualifying in the last two years, and finished bottom of their Europa League group this season - a far cry from the European adventures that Lennon instigated during his reign.
As it stands, they are four points clear of second-placed Aberdeen - with a game in hand - in a title race that would have perhaps been already settled in years gone by.
