Andy Robertson believes Liverpool have got the strength in depth required to maintain their thrilling pursuit of a first title for 29 years.

The Scotland left-back admits that confidence is sky-high after Sunday's 3-1 victory over Manchester United put the Reds a point clear of Premier League champions Manchester City.

Jurgen Klopp's unbeaten side are enjoying the best start to a top-flight season in the club's history having dropped just six points so far this term.

The Reds will guarantee top spot for Christmas if they win at Wolves on Friday night and then they face home games with Newcastle and Arsenal before the titanic clash with City at the Etihad on January 3.

“We are in December, we know how tough this period is but we are top of the league,” Robertson said.

“We have just got to keep going. We know how good Man City are, we have a bit of a gap that has opened up now to third. The two of us are close to each other but we believe we can stay top.

“There is a long way to go and we still have to play big games, starting on Friday night and we hopefully move on from there.

“It has been a huge few weeks. People maybe looked at the fixtures and thought ‘Everton, it’s a derby, always tough, Bournemouth, always tough, Napoli was a must-win and Man United speaks for itself’.

“We have come out unscathed but we can’t just rest on that and take our eye off the ball. We need to stay focused 100% and look forward to the challenge at Wolves who have done well this season. We'll rest and get ready for another big one.”

The depth of Klopp's squad was underlined by the contribution of match-winner Xherdan Shaqiri off the bench against United.

The Swiss attacker struck twice to ensure that momentum was maintained, while Nathaniel Clyne and Fabinho both caught the eye on their return to the starting line up.

“You look at the bench and there is probably a few people disappointed not to start and rightly so,” Robertson said.

“We have all got positions to fight for and that is the beauty of having a good squad.

“Shaq comes on and shows everyone what he can do and scores the two goals and he will take the headlines. Hendo (Jordan Henderson) came on and shored up the midfield, won every tackle, and never lost a header against (Marouane) Fellaini, which is always tough.

“These guys were disappointed not to play before kick off but they come on and make such a difference for us. It was a real all-round performance.”

“He is seizing his chance and good on him, you can use it to your advantage because you might go under the radar a wee bit,” Robertson said.

“There might not be as big a deal made about your signing but you can use that to your advantage because it takes time to get your feet under the table.

“Shaq has hit the ground running, quicker than I did, so credit to him. He has learned the way to play and he has been fantastic all season - a real threat for us and his stats this season are very good, so long may that continue.”

Robertson has been in outstanding form so far this season and his all-action performance against United even earned rave reviews from Jose Mourinho.

The United boss said he was “tired just looking at Robertson” who he described as “absolutely incredible”.

Typically, the modest full-back was keen to deflect the praise on to others.

“It is just part and parcel of my game, I will keep on going until the end,” he added.

“I got a bit of space, particularly second half and the gaffer is always banging on to me and Trent (Alexander-Arnold), more so this season, that we have to be more involved and I just tried to do that.

“Special mention goes to Clyney, being out for so long and my God, he did brilliantly. He has had his struggles with injury but he put in a first-class performance and that just sums up our squad at the minute.

“It was a very controlled performance by all of us. We just had a blip five minutes before half-time but other than that we controlled the game and deserved the win.

“We struggled against United last season. They beat us comfortably at Old Trafford and I think it was 0-0 here so they have been a bit of a bogey team.

“To put in a performance like that and get the result we needed is massive for us. It only takes us three points closer to where we want to go but hopefully it is a big step for us.”
