Arsenal is very inconsistent and would not be able to close fifteen points unless the unexpected happens. Arsenal would also be distracted by the UEFA Champions League since I assume they would qualify for the quarterfinals since they have a seven goals advantage. Newcastle is a good side with a dangerous attack, Liverpool would have to put more effort to win that Cup. Arne Slot would have to encourage his players to forget about the disappointing loss to PSG and focus on winning the Football League Cup.
In fact, with Liverpool being eliminated from the Champions League competition, they will be more focused on winning the Premier League title this season.
Liverpool are already quite comfortable at the top of the standings with a 15-point advantage and also no other team can be consistent so that Liverpool is without any pressure so there is no need to doubt that Liverpool can win the Premier League title this season, they are now really very confident to win the EPL title regardless of their elimination in the Champions League.
PSG dominated and made a path to qualify for the next round, Liverpool couldn't live up to expectations, the multitude were attached to them able to succeed in this round of 16 and make their way through any of the finals, sudden demise of Liverpool from the Champions League is unthinkable, no traces of weakness that should have hindered them from succeeding into the extended part of the competition. With two titles to win, it should now be the utmost priority after letting go of the one that is worth more, UCL victory would have been better compared to the total of what they will win this season.
