Tottenham will surely have themselves to blame because of how they handled the game during the last 20 minutes. 2 goals up is actually a scoreline that you can defend but they failed to. PSG on the other hand deserves some credit even though initially before the game they were the favourites but fell behind and had to fight in order to make a comeback and if which they achieved.
Tottenham held the game till it got to 10 minutes before the additional 4- 5 minutes extra time before the final whistle, Tottenham coach would have instructed his players to focus more on massive attacks and defense instead of choosing to go all back to defend when they don't have a solid defense yet. PSG took the advantage to launch countless attacks on them untill they were able to get a break through which saw them come back from 0:2 to 2:2 in the game, it was a surprising comeback but PSG deserves the win.
