Too bad Ajax didn't manage to score at least one more goal. They deserved it for sure and would make my bets pass perfectly. If they could have kept the intensity from the beginner of 2nd half I believe Juve would have cracked.
The other game went rather expected with Barca playing pragmatically on result. This is new quality in their game and possibly the most important one to win competition like Champions League. It isn't very enjoyable to watch but sure is effective.
In my opinion Ajax is a tought team and Juventus should be afraid of them in the 2nd leg.
They have so many young players that they want to achieve things and accomplish goals for their career improvement and disqualifying Ronaldo's Juve would be an important goal for them.
