Monaco were knocked out of the Champions League on Wednesday evening as they were beaten by Shakhtar Donetsk.
Trailing 1-0 from the first leg, Monaco needed a positive result in Ukraine to book their place in the group stages.
It was all going so well for the French side.
They led 2-0 at half-time thanks to Wissam Ben Yedder's first-half brace.
But it all fell apart after the break for Monaco.
Shakhtar forced extra-time thanks to Marlos' 74th minute strike.
Monaco would then have their hearts broken in incredible fashion with six minutes of extra-time remaining.
Mykhailo Mudryk stormed into the box down the left and tried to pull the ball back for one of his teammates.
The danger looked to be over when Ruben Aguilar intercepted his opponent's cut-back.
But Monaco would fall behind as the ball bounced off Aguilar's foot, lobbed the goalkeeper and nestled into the net.
It was a truly bizarre own goal and you can watch it below.
Football can be so, so cruel.
Monaco pushed for a winner but they could not find the goal they needed and thus crashed out of the Champions League.
