Liverpool happens to be the best team in the champions league now and I don’t think they can just play this game without putting any intensity into it. Just like the games they’ve played in the past and became victorious, they will still have another chance by them to win the match against PSV. This will not be a matter of qualification to them but for the records, they’ve won the game against the team.
Liverpool have already proven that they are the strongest team in the Champions League. Liverpool have won all 7 matches and are at the top of the table. The match against PSV is not important for Liverpool. Even if they lose this match, Liverpool will still be at the top of the points table.
I doubt very much whether Liverpool will give their full effort in this match. Because the next two matches are even more important for Liverpool. Liverpool will play against Bournemouth in the Premier League match. Bournemouth is in great form at the moment. And in the next match, Liverpool will face Tottenham in the semi-finals of the EFL Cup. So I will not be surprised if Liverpool does not give their full effort in the match against PSV.
The only team that is unbeaten in the Champions League at the moment is Liverpool and that makes them very comfortable to qualify for the last 8, so as you said it should be able to save their main squad in that last game and play young players or reserves to give them playing time at the moment, during can qualify for the last 8 of course ending the semi-league phase in 1st and 2nd positions at the moment should not be a problem for them, in my opinion instead of focusing on Eindhoven at the moment in the Champions League of course it is better for them to focus on the next match in the league against Bournemouth, because after all Bournemouth is not an easy opponent for them to face in week 24 later in the Premier League.
This week will be a hard one for Liverpool because they will have to play PSV in the champions League and also with Bournemouth in the English premier league, when it comes to the match between PSV and Liverpool in the champions League Liverpool has already secured their place in the knockout stages, having won all seven of their previous matches in the competition. According to rumors Manager Arne Slot has opted to rest several key players, including Mohamed Salah, Virgil van Dijk, and Alisson Becker, since the match really don't matter for them if they lose or win, so they need to rest players in other for them to play with Bournemouth, because losing a match with Bournemouth will risk there chances of them winning the premier league title and Liverpool don't want to take that chance so if there coach decides to rest his key players is a good move and will really benefit them and if this happens PSV will have more chance of winning the match today, PSV is currently in 19th position and really needs to avoid defeat from Liverpool today in other to secure a playoff spot in this seasons champions League, so they will play with there all.
