Andy Robertson began his youth career with the team he supports, Celtic, but was released at the age of 15.
Robertson then went to Queen's Park, where he broke into the first team before moving on to Dundee United.
English football then came calling, initially with Hull City before transferring to Liverpool, where he won it all.
With the Reds, the full-back has won the Premier League twice, the Champions League, the FA Cup, the EFL Cup on two occasions, the Club World Cup, UEFA Super Cup, and the Community Shield.
However, Robertson is now 31, and Liverpool signed Milos Kerkez from Bournemouth last summer as an alternative left-back.
Robertson has made just four Premier League appearances this season, so he could leave to secure regular game time.

Football Insider has reported that "Celtic would love the chance to bring Robertson to the club."
Andy Robertson could be a part of a Celtic rebuild
Brendan Rodgers has recently resigned as Celtic manager, with Martin O'Neill and Shaun Maloney taking charge on an interim basis.
The next permanent Hoops manager could be their former boss Ange Postecoglou, or Ipswich Town's Kieran McKenna.
If Robertson were to join Celtic, it could cause a tactical headache, as he plays in the same position as Kieran Tierney.
However, whoever their manager is could play Robertson as a wing back, with Tierney left of a back three, just as Steve Clarke has done with Scotland.
It would certainly be a fantastic story for Robertson to return to the club where it all started for him.
