Jurgen Klopp's side suffered a minor stutter during the month of January as they succumbed to back-to-back defeats against Swansea City and West Bromwich Albion in the Premier League and FA Cup respectively, but they have since sorted themselves to make valuable progress.
Van Dijk was pleased to see a protracted transfer saga brought to a close at the turn of the year, although he maintains that the uncertainty surrounding his future - first sparked when Liverpool were accused of making an illegal approach in the summer of 2017 - proved to be no distraction. Out of this, 23 of them have come in the Premier League campaign, where he has barely put a foot wrong this term.
"Liverpool's game against United is coming up on the horizon and Klopp's side have already given themselves a huge boost heading into that game after their 5-0 Champions League win against Porto", stated the ex-Ireland striker in his Sunday World column.
"The team spirit is good, and the confidence is here, so I think we're in a good way", Mane told Liverpool's official matchday programme.
"Every single player is always very happy playing with each other".
He added: "We continue to work up design, capacity and economic viability options for Anfield Road working with an architect to help with that process".
"I think City will be hard to catch because they have too many points but of course we can be second". We are third in the Premier League, we are still in the Champions League and I think we are in a very good position.
Virgil van Dijk acknowledged he has had to "step up" his game since leaving Southampton for Liverpool in a move he hopes will allow him to win "everything possible".
"We know that on our day we can beat any team in the world".
Selling Philippe Coutinho in January hasn't damaged the club irreversibly and although an FA Cup exit did occur in his absence, Virgil van Dijk's calming presence at the back has been the flawless signing to help forget about the Brazilian.
