If it's just a win, I'm sure PSG can get it, especially since the odds are low. There's no doubt that PSG can get 3 points from Toulouse even though it's considered a bit difficult. I only hesitate when choosing PSG for handicap betting to at least get @2,00 odds. Maybe you can include PSG in your combo bet list, but don't choose handicap, because we know that in their last 2 matches, they only managed to win by 1 goal difference.
Considering the two teams H2H, I agree that handicap bets are best avoided. Another consideration is that PSG have struggled to secure three points in their last two matches, which they should have won convincingly. PSG appear to be in inconsistent form at the moment, but this situation presents a high risk bettor with the opportunity to bet on a draw at odds of x5++. It's tempting, isn't it? And I'm quite confident Toulouse can deliver. However the safest bet is still a straight bet on a PSG win.
