If the round of 16 of the UEFA European Championship is any indication, we should be set for a mesmerizing final seven matches, because the eight knockout-round matches we’ve seen so far have been pretty much insane. Stars have missed penalty kicks, own goals continue to baffle and entertain, the defending world (France) and European (Portugal) champions were eliminated, and darling Denmark has romped on despite playing without star Christian Eriksen.

We’re left with four quarterfinals — Switzerland vs. Spain, Belgium vs. Italy, the Czech Republic vs. Denmark, and England vs. Ukraine — and have a few days to catch our breath.

Each round-of-16 game was nuts in its own special way. Here’s a quick look back at eight games to remember.

— Denmark, missing its best player, who nearly died on the pitch after suffering cardiac arrest in its group-stage opener, advanced to the Euro quarterfinals for the first time in 17 years with a thunderous 4-0 win over Wales on Saturday. It was the Danes’ second straight match with at least four goals, something that had never been done in the tournament, which was first contested in 1960.

— Italy, the most impressive team in group play, defeated plucky Austria, 2-1, in a match in which all three goals came in extra time. The Azzurri conceded a goal for the first time in 1,168 minutes of international play, a world record.

— Netherlands defender Matthijs de Ligt got a red card for a blatant hand ball on a goal-scoring opportunity in the 55th minute Sunday, and the Czech Republic took advantage with two second-half goals in a 2-0 win over a Dutch team that had won all three of its group-stage matches.

— Thorgan Hazard’s 42nd-minute goal was the only scoring as Belgium ended Portugal’s hopes of a repeat Euro title. The Red Devils hung on despite being without star Kevin De Bruyne for most of the second half because of an ankle injury. They also kept Cristiano Ronaldo off the score sheet for the first time in the tournament.

— Monday’s sheer insanity began with Spain’s 5-3 extra-time win over Croatia, which began the scoring when Spanish goalkeeper Unai Simón let the ball skip past him on a casual back pass from teammate Pedri. Spain recovered nicely for a 3-1 lead, but Croatia scored twice after the 84th minute to force extra time, only to have Álvaro Morata and Mikel Oyarzabal find the net over the final 30 minutes.

— Not to be outdone, defending World Cup champion France also surrendered a late 3-1 lead, with Switzerland scoring in the 81st and 90th minutes to even things up. And after a scoreless stretch of extra time, Swiss goalkeeper Yann Sommer — who at one point during the group stage had to leave his team to be with his wife as she gave birth to their second daughter — denied French star Kylian Mbappé during the penalty kick shootout, giving the generally unsung soccer nation its first trip to an international quarterfinal since 1954.

— Then, on Tuesday, England defeated old rival Germany, 2-0. It was the first time it had beaten the Germans in an international knockout-round game since the 1966 World Cup final and its first win over Germany at Wembley Stadium since 1975. Raheem Sterling’s third goal of the tournament broke a long-standing 0-0 deadlock, and Harry Kane’s header 11 minutes later sealed the deal.

— With the final round-of-16 game seemingly headed for penalty kicks, Artem Dovbyk headed in a perfect feed from Oleksandr Zinchenko in the 121st minute, giving Ukraine a 2-1 win over a Swedish team that played with 10 men for a good chunk of extra time after Marcus Danielson’s red card in the 98th minute. It was one final bit of nuttiness, the second-latest goal in Euro history (Semih Senturk scored in the 122nd minute for Turkey against Croatia in 2008).

And so the quarterfinals are set. More madness could be next.
