Robertson will wear the No. 26 shirt, and will link up with his new team-mates on their return to Melwood at the start of next week, as pre-season continues.
And as the Scotland international put pen to paper, this was reflected by fans on social media.
Andy Robertson to hopefully follow in the footsteps of John-Arne Riise

An initial £8m rising to £10m deal for Andy Robertson is stellar business, especially as #LFC will get almost as much for Kevin Stewart

Excited for Robertson, good signing imo

“Great signing; let’s face it he couldn’t be any worse than Moreno and great to have a Scotsman in the LFC team again—good luck! Now let’s push hard for the last two pieces of the jigsaw!
– Rob Mackenzie on Facebook.
Delighted with Robertson. A left back with a left foot and pace. Magic.

Robertson is a very very decent signing!

#lfc Robertson and Stewart in what practically amounts to a swap deal with Hull City. Well played Edwards.

Good business on Robertson if we've got 8 million on Kevin Stewart

“Well we’ve got ourselves a proper left back with premier league experience basically for nothing with Stewart going the other way so good deal in my opinion players aren’t born legends they turn into them and I trust our manager’s judgement welcome to Liverpool Andy!”
– Laura Harrison on Facebook.

Happy with Robertson. Time to end LFC's string of unconvincing LBs who are either dim, fond of aimless crosses or firing shots into the Kop.

“Decent signing, no every player is going to be a house hold name. Just look at Trippier at spurs who will turn into a top left back, everyone said no to him when we were linked because he played for Burnley. Hopefully this lad is better.”
– Abdul Sobur on Facebook.
Robertson has some breathing space, no real fee or expectation, hope he does really well

Karius, Clyne, Matip, Lovren, Robertson, Hendo, Lallana, Coutinho, Mane, Salah, Firmino.
To start the season as we stand, decent team.
