The former Liverpool defender is a big fan of the Scotland captain and has backed is former side to reach the Champions League final once again
Former Liverpool star John Arne Riise has identified Andy Robertson as one of the top left-sided defenders in the game and insists he is the "perfect" modern full-back.
Riise won a Champions League title with the Reds during his seven-year spell with the club, with Robertson now hoping to do the same as Liverpool look forward to their quarter-final second-leg clash with Porto.
Jurgen Klopp's side are 2-0 up from the first meeting, a game that Robertson had to sit out due to suspension, but as he prepares to feature in Portugal, Riise believes the Scot is up there as one of the world's top left-backs.
