Spain had embarked on its usual high-possession attack early in Monday’s Euro 2020 round-of-16 game against Croatia, with La Furia Roja employing a whole lot of passes until it could find a seam in the opposing defense.

Here’s what happens when high-possession attacks go horribly wrong.

Spanish goalkeeper Unai Simón’s extremely casual attempt to control a back pass from Pedri was a dismal failure, the own goal giving underdog Croatia a 1-0 lead in the early going. Pedri was credited with the goal, but it was clearly a joint effort.

“One of the strangest goals you’re ever likely to see in a major tournament, or even in a normal game,” ESPN announcer Derek Rae said.

Spain and Simón would recover: The goalkeeper made a number of stellar saves in an eventful 5-3 extra-time win that saw Croatia score twice after the 85th minute to tie the score at 3 and Spain answer with two goals in three minutes during extra time.

Spain will face Switzerland, which upset France, in the quarterfinals Friday.

There have been nine own goals in Euro 2020 group play and the early portion of the knockout round, which equals the number of own goals previously seen in the tournament’s entire history entering this year. Four of the own goals this year have been credited to goalkeepers. Spain now has been involved in three of the own goals; it also got two from Slovakia in the group-stage finale Wednesday.

Here they are, in all their shameful glory. Somebody cue up the “Curb Your Enthusiasm” theme music.
