Schalke - City, pretty easy
Atletico - Juve, close tie, but Juve should go through
United - PSG, straight forward really
Spurs - Dortmund, close, but BvB will beat them
Lyon - Barca, easy
Roma - Porto, could be close, Roma arent that good this year
Ajax - Madrid, if Real dont improve, this could be closer than people think. Ajax in great form.
Liverpool - Bayern, close, but Liverpool are too good for Bayern at the moment.
