Even though it's still early days, it doesn't matter because the odds can change as the tournament progresses.
Is PSG still your favorite? For us, it's Liverpool at the moment.
Even though they're not the favorites, they still have a chance, odds of 6 are good enough to take a risk, But i will choose Liverpool since AC Milan not going to any europe competitions. Well, we also need to remember if not many clubs have been able to defend their Champions League title for two consecutive seasons. So, if PSG also experiences this, there's a chance they could fail before reaching the final.
