Quarter-final second legs

Napoli 1-0 Arsenal (agg: 3-0)

The Gunners are through to the last four for the second season running after Alexandre Lacazette's fine first-half free-kick settled this tie as a contest. Napoli created more openings before and after the only goal of the night but Petr Čech was never stretched. Valencia await.

Valencia 2-0 Villarreal (agg: 5-1)

Left-back Toni Lato scored his first senior Valencia goal with a composed first-half strike in abysmal conditions. Debutant right-back Andrei Ratiu's error led to the opener, and Dani Parejo's wickedly deflected free-kick sealed his side's second-leg win after the interval.

Eintracht Frankfurt 2-0 Benfica (agg 4-4, Frankfurt win on away goals)

Goals from Filip Kostić and Sebastian Rode helped Frankfurt overturn a 4-2 deficit. The home side were straight on the front foot and were rewarded when Filip Kostić scored after Mijat Gaćinović had hit the post. Sebastian Rode fired in after the break after a pass from the excellent Ante Rebić, sealing an away-goals win.

Chelsea 4-3 Slavia Praha (agg: 5-3)

Chelsea scored four before the break and equalled Atlético Madrid's competition record of 15 games unbeaten. Pedro Rodríguez struck the first and last goals of a thrilling opening half in which Olivier Giroud grabbed his competition-leading tenth of the campaign. Slavia made Maurizio Sarri's men toil, though, thanks to two wonderful efforts from Petr Ševčík after the interval.
