The midfielder joined from Hibernian in May 2007 in the biggest ever transfer between two Scottish clubs. He made a total of 142 appearances for Hibernian in five years as a first team player, scoring 21 goals and helping them win the Scottish League Cup in 2007.
It was Gordon Strachan who brought Brown down the M8 and made him a Celtic regular, pushing him into a more central midfield role in what was a slight change to his time at Hibernian where he was used to playing off of the strikers.
But Brown adapted to the new position and began to establish himself in the Hoops. Tony Mowbray handed the Scotland internationalist the captain's armband following the departure of Stephen McManus in January 2010. But it was during his first season under Neil Lennon where Brown stamped his authority on the new-look squad.
Known for his drive, determination and passion on the pitch, he is one of the most valuable players in the current squad and has captained the team to four league titles in a row, as well as to a league and cup double in the season 2012/13.
In what was a blow to new Hoops' boss Ronny Deila, the captain suffered a pre-season injury at the very start of the Norwegian's maiden campaign, forcing Brown to miss the first couple of months of the season.
However, Brown would return in fine form, earning himself a new deal that committed his future to the club until 2018. The captain's contribution to the Bhoys' season saw him share the 2015 Players' Player of the Year award with fellow midfielder Stefan Johansen at the annual Celtic Player of the Year awards.
