There was no question as to the hero of the hour as Mislav Orsic scored a hat-trick, but the defeat raises fresh questions over Jose Mourinho's future at Spurs.
✔️ DOMINIK LIVAKOVIC: 7.4
Tottenham did not exactly lay siege to the Dinamo Zagreb goal - they only had four shots on target over the course of the match - but the home goalkeeper more than earned his crust with a couple of fine saves as the pressure built in extra-time.
A stop from Kane with time running out was a particular highlight. At that moment, Dinamo must have felt it was to be their night.
❌ DELE ALLI: 5.8
Dele Alli seemed to have won some credit in the eyes of Mourinho in recent weeks after being scantly used this season. Much of that was frittered away in Croatia, where he produced a miserable performance that stood out even among an abject Tottenham team.
⭐ MISLAV ORSIC: 10
Will the 28-year-old enjoy a better couple of hours on the football pitch in his life? Probably not.
The attacker, who has been in excellent form for Dinamo Zagreb in the Europa League throughout this season, was their outstanding player once more.
He drilled the opener from range, added a second with a brilliant solo goal to force extra-time and then won the game during that additional period by completing his hat-trick.
