Big teams remain in the third-tier UEFA Conference League after Chelsea, Fiorentina and Real Betis all advanced to the semifinals.

Chelsea's 3-0 first-leg win against Legia Warsaw meant it would have taken a remarkable turnaround at Stamford Bridge to prevent the two-time Champions League winners from progressing.

And, despite a 2-1 loss in Thursday's second leg, Chelsea won 4-2 on aggregate to move on.

Fiorentina needed Moise Kean's second-half goal to draw 2-2 at home against Slovenian club Celje and secure a slim 4-3 aggregate win.

Betis advanced 3-1 on aggregate over Jagiellonia Bialystok of Poland after a 1-1 draw in Thursday's second leg.

The most dramatic result of the day saw Swedish side Djurgarden score two goals in extra time to defeat Rapid Wien 4-1 on the day and 4-2 on aggregate.

Djurgarden will take on Chelsea in the semifinals of the competition, while the other side of the bracket features an intriguing semifinal clash between Fiorentina and Betis.

The semifinals will be played May 1 and May 8. The Conference League final is slated for May 28 at the Stadion Miejski in Poland.
