Forrest enjoyed a memorable debut by scoring a wonderful goal against Motherwell at Celtic Park in a 4-0 SPL win on May 1, 2010.
The winger is a product of the Celtic Youth Academy and began to push into the first team after picking up league, Scottish Youth Cup and Glasgow Cup medals as a teenager.
He travelled with the first-team to take part in the Emirates Cup 2010 and won the Young Player of the Tournament award, helping him force his way into the Celtic first-team.
His rapid progress has continued unabated over the past few seasons, and in January 2012 he was named by FIFA as one of the brightest young talents in world football.
Forrest is now an established Scottish internationalist, having made his debut against Ireland in May 2011.
Plus, in Europe, he would score a crucial last-minute winner for Celtic to secure their comeback against Shakhter Karagandy to seal their place in the UEFA Champions League group stages.
Having battled with injuries, Forrest featured in Celtic's first game of the 2014/15 season against St Johnstone before scoring his first goal away to St Mirren in December of 2014.
Forrest would follow this up by scoring the winning goal in this season's Scottish League Cup when he bagged Celtic's second, to secure Ronny Deila's first trophy as Celtic manager.
