It’s normal in football to apply the parking bus strategy when you’re leading especially in a final. Tottenham really played well but they unlucky in the second half their defence couldn’t hold out the Attack of the PSG team, I’ll say maybe they didn’t have the players to defend properly or the changes also affected them.
How does the parking bus strategy work in the football match?, actually Tottenham has players who would have defended very well till the end without failing but is just there fault, if we say they don't have better defense who defended all the attacks that was coming from PSG on the first half?, it was actually how tough there defense was that PSG couldn't score on the early time but some mistakes they did spoiled the perfect defense they had organized and became very bad to defend, Dembele took many shots for the opportunity he got but wasn't quite well from what he saw on those attempts.
