The Reds signed the Scotland international in an £8m deal from Championship side Hull City in the 2017 summer transfer window.
Robertson was drafted in to provide greater competition for places at left-back after Jurgen Klopp was forced to use James Milner at full-back last term.
Alberto Moreno started the season as the German’s first-choice left-back despite Klopp overlooking the Spain international throughout the 2016-17 season.
However, the former Sevilla star suffered an injury in early December to present Robertson with the chance to lay claim to a starting spot.
And the Scottish defender has seized his chance to impress with four assists in 19 games in the Premier League over the past four months.
Robertson’s performances have been overshadowed by Mohamed Salah’s incredible return of 29 goals in 31 games this term.
Former Liverpool FC captain Redknapp hailed Robertson as the “bargain of the season” following his impressive impact at the Anfield outfit.
“Left back is one of the more difficult positions to fill,” Redknapp told the Daily Mail.
“Crouchy went for Ashley Young, who has forced his way back into the England team, but I would have gone for Liverpool’s Andy Robertson.
“He was relegated with Hull last season, and that can leave a mental scar, but he has thrived at a big club. Defensively tough, Robertson is also dangerous going forwards and he made Liverpool’s winning goal at Palace.
“When you think Manchester City spent £133million on full backs last summer, at £8m Robertson is the bargain of the season.”
Liverpool FC are in third place in the Premier League table and 10 points ahead of fifth-placed Chelsea FC, although the Blues have played one game less than Klopp’s side.\\
