Yesterday's round brought no surprises in terms of who got qualified, but it shed some light on possible vulnerabilities of two clubs that were/are considered favourites.
Both PSG and Barcelona conceded 3 goals each, proving their defences are not as solid as some could think and that both can be defeated. Of course, they might not have played at their 100% due to the advantage from the 1st leg, but it's not like they lost on purpose. And, for PSG, the last minutes were pretty stressful as Villa was close to equalising.
With this in mind, while betting on the outright winner, it wouldn't be a bad idea to bet on underdogs.
As for today's round, I think betting on Real to win is a fairly safe option. I don't think they will qualify, but a minimal win is the most likely outcome.
