I chose both to score on Barca game @1.7, should be an easy bet to win for reasons you mentioned above and Barca can score one goal even if they are playing with juniors.
Then I went with Dortumnd -1.5 @1.9, hopefully Haland wants to build his CL stats a bit
PSG to win @1.7, seems to me this is the time for revenge and if they loose they are basically out of CL which would be a big hit for them
I really ought not to bet tonight but urgh I went ahead and put 2 more parlays for today (actually, games already started so can't make those bets now, not that anyone follows me haha) have very high confidence in Sevilla, Lazio, Chelsea. One will probably disappoint me but anyway.
Haaland will score, don't know if his team will provide good service though, but that man is a machine. PSG should also win, but not sure about must-win games these days.
All in all, yeah a tepid 4th Match Day it looks on the cards.
