Clearly, Celtic fans absolutely love their captain and midfield monster Scott Brown, but at the age of 33-years-old and with his 34th birthday coming up in June, the Parkhead skipper doesn't have long left. As Neil Lennon, or whoever else takes on the Celtic job, is tasked with looking for a Broony replacement, they need only look as far as Callum McGregor.

Scott Brown may be one of the most iconic men in Scottish football. Everyone knows the scene, the veteran Scot has just scored, the Parkhead atmosphere is electric and the midfield man just stands there, arms aloft, screaming in delight. Soon, that will be just a memory and not a common occurrence, if Scott Brown scoring was ever common, but it could be set to get better for the Bhoys in his retirement.

Scott Brown has made a name for himself at the base of the Bhoys' midfield, and whilst Callum McGregor has been going about his business much further up the pitch it could be a good opportunity for him drop deeper as he looks to fill the shoes of his surely soon to depart captain. Perhaps it's not imminent but, obviously, Brown may have a couple of seasons left in him, but sooner or later it will be up to McGregor to replace the iconic Scot.

McGregor has plenty of time to learn the ropes of the deeper midfield base. He has featured there before but is more comfortable when playing further up the pitch in the #10 role in front of the Parkhead crowd. What he does have, though, that's key for the role is reliability and durability. This season has seen the Scot feature 57 times for Celtic in all competitions, a remarkable stat in itself.

In those 57 appearances, he's contributed six goals and 15 assists, and if he can carry on producing numbers similar to that whilst operating from Scott Brown's deeper role then he'll be well placed to not only act as his skipper's replacement but also an improvement. There is no shame in admitting that Brown is starting to show signs of his age, and if McGregor can come into his position and add some life next season, slowly phasing out the 33-year-old it would be a step in the right direction.
