A Glaswegian born in 1994, Robertson was on Celtic’s books as a schoolboy but released when he was fifteen. He went on to join Scottish League Two amateurs Queens Park, forcing his way into their first team for the 2012/13 season before being signed by Dundee United. After an impressive season, he was named PFA young player of the year in Scotland, having scored three goals from the left-back position. He also made his Scotland debut whilst still a teenager in March 2014, coming on as a second-half substitute against Poland in Warsaw.
In the summer of 2014, Robertson joined Hull City where Robertson had an eventful three years. He was twice relegated from the Premier League as well as being promoted from the Championship. He made 99 league appearances, scoring three times and continued to be called up by Scotland, scoring his first international goal against England in a friendly at Celtic Park in November 2014.
Robertson joined Liverpool on 21 July 2017 in a deal reported as being worth as much as £10million. He expressed a desire to prove he can perform at the highest level and Jurgen Klopp told reporters he believed it was the perfect move for him. He said ” For Andrew, this is another big step on what has been quite an incredible personal journey in a very short space of time. I know our environment will benefit him and help him push himself even more than he has already. This is a player who does not limit his ambition.”
