A few eyebrows were raised on Merseyside when Jurgen Klopp decided to spend £8 million on Andy Robertson last summer.
Why would Klopp decide to shell out that fee on a player that had just been relegated with Hull?
At the time, it did seem like a bizarre signing. But what a signing he has turned out to be.
The Scotsman was made to wait for his debut at Anfield, with Alberto Moreno the number one choice at left-back.
But when given the chance, he took it with both hands. He eventually made 29 appearances in all competitions, scoring once.
Liverpool fans were so impressed with him, that they gave him the second highest rating of all the team’s players this season, behind only Mohamed Salah and in front of the likes of Roberto Firmino and Virgil van Dijk.
Van Dijk has also made a big impression since signing.
The Dutchman has actually played Robertson before, when the two were plying their trade in Scottish football.
And Van Dijk has revealed what he made of Robertson when they played against each other for the first time in 2013, in a meeting between Dundee United and Celtic.
The left-back was only 19 at the time, but Van Dijk was so impressed with the Dundee United man that he told Celtic to sign him after the game.
“Robbo is doing fantastic. Obviously when I came to Celtic, in my first season he played at Dundee United and I already thought he’s a very good player and I thought at that time he should join Celtic!” Van Dijk said.
“I think I said it to one of the scouting guys as well – sometimes I like to give my opinion on players.”
Van Dijk has clearly admired Robertson for some time.
The Scotsman replied to Van Dijk’s kind words on Twitter.
Frieeenddsss! What a man ❤️ https://t.co/O7cr00TAhT

The Dutch defender also added that he enjoys playing with him at Liverpool as he raved about the 24-year-old’s consistency.
“He’s just a great player, [he] works hard,” he added. “If you need ratings of a game, I don’t think he’d ever go lower than a six.
“You can trust him and the connection I have with him is getting better every game. He knows obviously what he has in me, and I get it the other way around as well. He’s a good guy as well and that obviously helps too.”
