Manchester City are out of the Champions League after Monaco struck late to seal a thrilling away-goals victory, which ended 6-6 on aggregate, condemning them to a painful exit on away goals.
Trailing 5-3 from the first leg in England, teenage starlet Kylian Mbappe put Monaco ahead on the night after just eight minutes at the Stade Louis II and Brazilian midfielder Fabinho converted the home side’s second just before the half hour.
Leroy Sane’s 71st-minute goal handed City a 6-5 advantage on aggregate, but Bakayoko turned home Thomas Lemar’s free-kick 13 minutes from time as Monaco claimed a famous win.
Monaco go through to Friday’s draw for the last eight in Nyon carrying French hopes following Paris Saint-Germain’s shock elimination, while Guardiola suffered his earliest Champions League exit as a manager.
“We played an exceptional second half, but the first one we forgot to be there,” Guardiola told BT Sport.
“In the second half we were much, much better but it was not enough. It happens and we’ll learn, we have a team with not a lot of experience in this competition.”
Monaco hero Bakayoko will miss the first leg of the quarterfinal through suspension but was delighted to advance.
“It’s an immense joy to score in the Champions League. I didn’t expect this,” he said.
“Over two games we deserved to qualify. Now we want to keep going.”
