WATCH: The moment Andy Robertson made himself a Liverpool cult hero v Man City

Andy Robertson is looking like a right bargain at the moment.

The Scotland international has been in terrific form for Liverpool in recent weeks, making the left-back spot his own in the prolonged absence of Alberto Moreno.

Last season, Jurgen Klopp had to call on James Milner to deputise in the defensive role but now, he has a man tailor-made for the position, one who contributes heavily to the attack as well.

In the 4-3 victory over Manchester City – which brought Pep Guardiola’s unbeaten run to an end – Robertson turned in possibly the finest display of his professional career.

He nullified the pantomime villain Raheem Sterling and was a constant threat when bombing forward.

And, there was one moment late in the second half – when Liverpool were three goals ahead – that simply epitomised his commitment to the cause.

The left-back charged all the way up the pitch and sprinted towards Ederson to maintain Liverpool’s high-press.

Has anyone ever performed Klopp’s ‘gegen-pressing’ philosophy as well as this?

That is some stamina as well after a tiring game.

Liverpool fans were raving about the former Hull City man and not just for that one moment, but for his whole performance at Anfield.

There are still some bargains out there in football, as he only cost ยฃ8m.

LIVERPOOL FANS FALL IN LOVE WITH ROBERTSON

Deserved praise.

Liverpool now look real contenders for a top three spot after Chelsea’s 0-0 draw with Leicester on Saturday.

They’re now unbeaten in 18 games in all competitions and face what should be a relatively easy test when they travel to Swansea next weekend.
