The Reds were at their brilliant best as they thrashed the Gunners at Anfield to help them to move nine points clear at the top of the Premier League table.
Arsenal had taken the lead through Ainsley Maitland-Niles in the 11th minute, but Liverpool FC were soon level thanks to Roberto Firmino’s equaliser.
The Reds then when ahead in the 14th minute when Firmino fired home, before goals from Sadio Mane and Mo Salah’s penalty made it 4-1 at half-time.
And Firmino added further gloss to the scoreline when he fired home his penalty in the 65th minute to complete his hat-trick.
Robertson featured for 83 minutes at Anfield before coming off and had a pass success rate of 69 per cent.
And McManaman was clearly impressed by the Scot’s performance and overall contribution to the Liverpool FC team recently.
Speaking during BT Sport‘s coverage of the game, McManaman said: “He’s been absolutely fantastic.”
He continued: “He was patient to get in the side.
“More importantly, when he did get in the side, his passion, performances and work-rate has been absolutely outstanding. His numbers must be frightening.”
Liverpool FC will return to Premier League action on Thursday when they take on Manchester City at The Etihad.
