Liverpool are still at the top of the standings with 60 points but now they will not be able to maintain the top of the standings safely because Manchester City have also bagged more wins with total of 59 points, their difference is only 1 point and this is very possible for shift to occur at any time.
If Liverpool really make mistake that causes defeat then they will definitely go down if Manchester City continues to win and can get full points in every match.
You're right, I don't think Liverpool will be able to hold onto the top spot in the standings with the players they have available, if their injured players don't return in a few weeks. Manchester city currently with 59 points, Manchester City and Liverpool are separated with one point, which is not safety for Liverpool. However, it's not as though they can only lose their position to Manchester City, if Liverpool lose any of their games, Arsenal will pass them in the standings. We all know how strong Arsenal is right now they can defeat any Premier League team. I think Klopp should hope that Mohamed Salah with the other key players can return as soon as possible. Because their absence will effect their performance.
I said earlier that Liverpool can't stay at the top of the Premier League table for long with their current squad. If Liverpool's injured players are not yet back before Liverpool finishes playing their next three matches in the league, either Manchester City or Arsenal will be at the top of the Premier League table.
