Kieran Tierney is playing with a smile on his face as his career at Celtic continues on an upward curve.
The 19-year-old left-back has been one of the many star performers in Brendan Rodgers' Ladbrokes Premiership-winning team who remain unbeaten domestically this season.
Tierney has continued his progression under the Northern Irishman and has become a feature of Gordon Strachan's Scotland squad.
The former Parkhead youth player, who is savouring every minute of the campaign and preparing for the visit of Partick Thistle tonight, said: "I have worked hard every day, as I did last year, and hopefully I have improved as a player. I enjoy every game for Celtic, no matter what game it is. That's what I am here to do, play with a smile on my face.
"I have been lasting 90 minutes easier this season and played more games consistently.
"The training has been a lot harder so the fitness has come from that.
"The manager says my composure has improved from the games he watched of me last season, and I have more assists this year as well, but there are little bits of my game I need to work on."
