There are still enough games for Liverpool to make a come back and revive their league hopes for the season. With just 14 games already played in the league this season there are 24 more games to play which should be enough to get back into the game and still finish in top four. I am not so much concerned about Newcastle being in the top four position because I have a feeling they will have a bad form and drop points.
In fact, there is plenty of merit in Liverpool's team's return to form. I would like to say in accordance with your words, now there are many matches, if the Liverpool team wants, they can return to a good position in the league. And I also believe that the type of players that Liverpool have in the squad, if they perform well, they will surely secure a good position in the league.
With the big name Liverpool now bears, they should be able to return something they have lost in the 14 matches they have played. There was still time for them to catch up to the teams that were now above them. 7 points from 4th place is not a very wide gap, so they still have a chance to do it. After all, it's still very possible for a team in that position to lose a lot of points.
