Juventus must be able to win at home when hosting PSV even though the PSV team has better motivation when they were able to beat a strong team like Liverpool in the Champions League this season in the previous standings. However, for the match in the play-off round, I think both teams must play better because PSV also should not underestimate the Juventus team even though the team is not very consistent if we look at its current domestic league. Because in the Champions League, each team has a very different motivation when facing any opponent.
In a knock out phase like this, Juventus can use their experience and traditional defense and counter attack tactic of Italian football, to beat PSV. Juventus are not too strong in attacking as they shown in many matches so far, but if they can defend well, and sacrifice ball possession to PSV, I believe that PSV will show some weakness in defense. It will give Juventus some opportunities to exploit with counter attacks, but their attacking players must play well and even better than their usual performances in this season.
Juventus have more star players and I'd like to choose them than PSV, but with inconsistent form of Juventus, PSV will have chance to win as well.
They "can" but that doesn't mean that it will work. Just because they are good at defense, and great at counter attacking, and used that to win some games this season, doesn't mean that it will work in this case as well.
It just means that they are trying to do that for their own good, but we have no idea how things will look, so we are going to just assume and that's what we are doing but we could be wrong too. PSV has been great so far, they have beaten many good teams, and I am sure that it is going to be a tough game for both sides without a doubt.
PSG seems like the favourites to me, I understand not many will think like that but right now that seems like the case because that is what they have shown during UCL performances at group stages. I could be wrong, maybe Juventus will play that counter attacking beautifully and they will get a win out of that, it is not impossible and I am sure that we are going to see that mean something, but so far it is not that crazy.
