I'm not sure if Liverpool's present squad can stay at the top of the Premier League table before their key players return from injury. Even without key players, Liverpool was supposed to win against Luton Town yesterday because Luton Town only won five of their 25 matches played in the Premier League this season.
Liverpool did win when playing at home when they hosted Luton Town because that team was a weak team that Liverpool could easily face.
Liverpool failed to win the previous match against Luton Town. The match was drawn 1-1. Liverpool were lucky in the match to score in extra time after 90 minutes to draw the match. Otherwise Liverpool would have lost the match.
We saw Liverpool's dominance in the previous match as well. Even then they could not break the defense of Luton Town. Luton Town's players performed well in the first half of yesterday's match. But in the second half, Liverpool coach Klopp changed his match strategy. And in the second half we only saw the dominance of Liverpool players. After trailing 1-0 in the first half, Liverpool scored four goals in the second half.
And to be able to stay at the top of the standings until the end of this season, Liverpool only needs to win and not lose or hope to lose to Arsenal and Manchester City, both of which are very serious competitors for Liverpool this season. However, if we look at several Liverpool players who are still injured at the moment, of course some people really doubt that Liverpool will be able to survive for long at the top of the standings.
If you want to keep the top spot in the table and win the title, you have to maintain the winning streak. There is no alternative. Liverpool are likely to lose the top spot if they lose just one match. So now Liverpool team has to win every match consistently. Arsenal and Manchester City are doing their best to grab the top spot.
