His strategy make Tottenham lose, in the last 20 minutes Tottenham is playing with parking the bus strategy, they gather many players in their back, but they didn't mark any player. That's why Kang In Lee can score outside the box, Tottenham's players are just protecting in their box.
PSG actually not playing as good as before, we can see Doue isn't fit to play in central midfield position.
Watching Tottenham without Kane or Son feels weird.
If not for that change, PSG would not have been able to win that game. It was annoying, to be honest, because from the start of the game, when I saw PSG’s performance, I knew it was a bit poor. Tottenham were really serious, and they were able to defeat them in the game, but unfortunately, those chances near the end of the game made them lose everything. PSG knew that if they could make a draw in the game, then they would be able to win in the penalty shootout, which is exactly what ended up happening, as they equalized in the extra minutes.
Although this might affect PSG in the future, everyone knows that if you keep a good midfield, PSG will not be able to win the game. Their performance might shake this season, as they may not be able to do as well as the previous season.
