Don't think the momentum is with them. It's not like they have reduced 50-70 % of our lead. How could a single draw in 13 league games switch the momentum? Also, virtually all non-Liverpool pundits agree that two of their goals yesterday shouldn't have stood. They were poor in the 2nd half because they played 4 games over 10 days. Now imagine them playing 12 games over 30 days, with some of those games (Chelsea, Inter...) way more difficult than Brentford and Palace. They will have more options to rotate with Salah, Mane, Keita back from Cameroon, but all these games every 3-4 days after the break will tire them down at some point. They are an excellent team and Klopp is a top manager, but reality is that they are likely to suffer.
We are in a great position and, unlike last season, most of our players will be well rested for the final months. Only Bernardo has played a lot of minutes so far, and to a lesser extent Cancelo. But they will have a good rest now.
By contrast, the likes of VVD, TAA, Henderson, Fabinho, Salah, Mane have played a lot of football, the latter 3 will play during the break as well. Also, they have to chase the cups, otherwise they may finish with empty hands the season. Every single game is crucial for them now. That may help them initially, but it's tiring both physically and mentally. Even if they don't drop points in March, which I don't think is likely, they will experience fatigue in the final 5-6 weeks. Most of their key players are around 30, they can't recover as quickly as 3 years ago. Time will tell.
