Kris Commons has admitted he missed not playing Rangers when they were sent to the bottom tier of Scottish football in 2012.
Commons spent six years at Celtic Park, winning five league titles, two Scottish Cups and a League Cup during his stay in Glasgow.
However, despite his success, the 32-year-old admits that while he got his head down and concentrated on football when Rangers were in financial trouble, he also missed playing against Celtic’s Old Firm rivals.
Commons told OpenGoal, “As soon as the fixtures come out that’s the one [the Old Firm derby] you look out for.
“You can tell, there is an extra snap in your training because everyone wants to play”
“You just knew how big they were, not just for yourself and your family, but for the fans – it was massive,” he added.
The former Scotland international also mentions how playing teams like Barcelona was not only a physically draining experience, but one that also took it’s toll mentally.
He admitted, “You start getting cramp at 45 minutes, 60 minutes and you’re thinking ‘this shouldn’t be happening.’
“We always used to say, listen after 15 minutes you’re going to be breathing out your ring, just wait for your second wind and relax.
“I mean you’re looking at Messi, Xavi, Iniesta, Fabregas, Pique… they are just technically brilliant.”
Commons, who now does punditry work for BT Sport, went on to assess Deila’s time in charge of Celtic and went into detail over how much weight each player was expected to lose.
“He [Deila] didn’t have the minerals for the job that was in hand, he felt too under-pressure.
“There was a guy coming in saying ‘you’ve got to be under 80 kilograms’, which is fine if you’re 81 but lads were 84, 85 kilograms, losing best part of a stone in weight and then trying to play football.”
Commons’ time at Celtic came to an end at the end of last season, following a loan stint at Hibs.
