#2 Been there, done that
Barring the fact that Ajax remains the only team to knock out Real Madrid since Juventus, teams like Bayern Munich and Benfica failed to get better them as was evident from the group stages. The manner in which they knocked out Real Madrid, coming back from a loss in their home leg to score four goals at the Santiago Bernabeu shows the quality in the current team.
It goes without saying that the young Ajax side will be on the pitch with less pressure as Juventus has more to lose, which will benefit the Dutch side. If the approach of Ajax remains the same, the Bianconeri will be on the defensive from the first minute of the game, which can lead to the Dutch side entering a familiar circumstance.
Ajax had pulled off positive results when no one gave them a chance and there is no reason to believe they cannot pull off another miraculous result against Juventus led by Cristiano Ronaldo.
