You don't need to relax until the referee blow the final whistle. Tottenham coach got confident that we have won the game and did some wrong substitutions that gave PSG chance to score two goals in final moment of the game. Not many times we have seen in final, teams conceding crucial goals in final moment of the game. PSG recently lost to Chelsea in FIFA Club world cup and it will be their second major defat in a row but they somehow escaped that. It was an excellent opportunity for Tottenham to beat one of world's finest club.
Yes, it was a great opportunity, but they lost it. Tottenham could have done much more and not let the final slip away from them. Of course, this final doesn't count for much and even if they had lost it, it wouldn't have changed much, so I say that in the end they tried without any problems. This is a cup that really doesn't count for much.
