Right now that's how the Round of 16 is looking like:
Group winners: Man Utd, PSG, Roma, Barcelona, Liverpool, Man City, Besiktas, Tottenham
Group runners-up: Basel, Bayern, Chelsea, Juventus, Sevilla, Shakhtar, Porto, Real Madrid
So we could get Basel, Bayern, Juventus, Shakhtar, Porto or Real Madrid. Some pretty good teams there!
