Tottenham were found wanting defensively against Juventus.
His comments came after Juventus were held by Lazio for 90 minutes at the weekend before Dybala scored an injury time winner, with Allegri suggesting his side would find it easier to score. He told ESPN: "Tottenham are different compared to Lazio, they don't defend as well."
While these comments were picked apart by Tottenham fans who pointed to their quality defensive record, he had a point.
Without the injured Toby Alderweireld for both legs, Tottenham were exposed, conceding four goals in two matches, a tally which would have been higher had it not been for Juventus' poor first leg finishing.
No Alderweireld is an excuse, and reason to worry, amid reports he will be sold this summer amid his contract dispute, report The Mirror.
This is why moving to sign Stefan de Vrij makes more sense than ever for Tottenham, providing they can make the wages work.
De Vrij was part of the Lazio team which performed strongly against Juventus at the weekend at the heart of a back three.
The Dutchman has rejected a new deal and is available to sign on a free transfer this summer.
Allegri's comments, Tottenham's blip against Juventus and concerns over Toby Alderweireld mean Tottenham should take seriously the option of signing the defender.
With chairman Daniel Levy known for eyeing a bargain, this now makes more sense than ever before.
