The Reds went behind early on at Anfield through Ainsley Maitland-Niles, which served as a setback after the boost of Tottenham‘s 3-1 loss to Wolves.
“Obviously we know they’re dangerous on the break, with the speed of their counter-attacks,” he reflected.
“It was unlucky we conceded, but we reacted how we should have reacted, and deserved it today.
“We still need to improve a lot of things, but we’re very happy with the situation at the moment.
“We want to keep going, keep working hard and keep the intensity high, make sure we keep doing well.”
The nature of Liverpool’s lead at this stage has led to mounting expectation on Merseyside, and the Dutchman showed his confidence as he responded to a question on the possibilities of the months ahead.
“Anything. That’s how we should go out there and play: anything is possible,” he continued.
“We’re on a good way, we feel good, it’s tough these days but now it’s a great time to be a Liverpool player.”
The Reds make the trip to the Etihad on Thursday, and can now enjoy a relatively long stretch to prepare for one of the biggest games of the season.
This will be crucial for Robertson, who was again replaced by Nathaniel Clyne in the second half as Klopp continues to manage his minutes during a busy campaign for the Scot.
And speaking to BT Sport, the left-back conceded that rest will be required as Liverpool can finally turn their attention to the side built up as their biggest rivals.
“It’s a huge one, one everyone outside of the squad’s been looking at,” Robertson said.
“We’ve taken care of business in December, which isn’t an easy task. Now we go into the New Year and we look forward to it.
“City’s going to be a big game but we have a healthy lead, we’ll need to be 100 percent but I’m sure we’ll rest now and be ready.”
