Andrew Robertson produced yet another brilliant performance in Liverpool's 4-0 Champions League win over Red Star Belgrade.The energetic left-back has become a fan favourite at Anfield since breaking into the Liverpool first team last season.Robertson - who has quickly proven himself to be a top-class wing-back - was made captain of the Scotland national team in September.The 24-year-old former Hull City man looks certain to be a regular at Liverpool for years to come.He bagged an assist in Wednesday night's emphatic 4-0 win over Red Star.Towards the end of the game, legendary Liverpool left-back John Arne Riise responded to a tweet from a journalist.The Mirror's Jim Boardman asked his followers: "When did #LFC last have a left-back as well loved as Robertson?"

Riise, 38, spent seven years on Merseyside and responded to Boardman's tweet within minutes.

The Norwegian full-back scored 31 goals in 348 Liverpool appearances, earning a reputation for his fearsome left-footed thunderbolts.

He nailed his response - it's only been 10 years since Riise left Anfield to join Roma.

Robertson has quickly endeared himself to the Liverpool supporters but he's not yet as popular as the legendary Scandinavian.

Earlier in 2018, Riise claimed he was not convinced when Jurgen Klopp paid Hull £8m for Robertson's services.

"To be honest, I didn’t see it coming," admitted Riise in March. "I didn’t understand why Liverpool bought him in the beginning.

"People were talking about getting a big name player at left-back.

"He impressed me from his very first game – showing lots of energy and showcasing the aggressive side to him.

"He’s aggressive, he’s offensive, he’s quick and he never stops running. He is for sure the future."

Robertson has rapidly become key to Liverpool's on-the-field success, playing every minute in the Premier League this season.
