"Ali on the ball is unbelievable and you have to trust him in those moments," Robertson told reporters post-match. "It came from their corner or free-kick and Ali has got it in his hands and you trust him to make the right decisions.

"It's something we trust Ali with, he's unbelievable with the ball at his feet. He's got great vision as well and when he sees something, then we have to react off it and we all pushed up and luckily the ball has ended up in the back of the net.

"I think Ali's the best in the world for sure in what he does. We've all probably let him down this season in that he's faced too many shots, he's had to be making too many saves. I think he'll be a lot happier."

Liverpool now look to follow up the confidence-boosting win over Man City when West Ham United arrive at Anfield on Wednesday evening.

The 7.30pm BST meeting with the Hammers is a chance for Jürgen Klopp's men to make it three wins from three in all competitions and build up some winning momentum.

Robertson continued: "We were obviously brilliant but we need consistency. We've had a couple of performances this season where people have said, 'Can this kickstart the season?'

"It's important, it's such a big win for us against an unbelievable team that put us under so much pressure. But it's only a massive three points if we use it to our advantage.

"This performance was an excellent performance but it's important we all don't get too carried away.

"We have to do it consistently now. That's what our success has been built on in the past: being consistently good, consistently getting results and when you don't play well, still getting results.

"We've not done that this season and that's why we're in the position we're in."
