Zeki Celic gave 2023 runners-up Roma the lead in first-half stoppage time in Portugal, but Porto defender Francisco Moura's deflected strike ensured the teams will head to Italy next week with the tie finely poised.

Roma played the final 18 minutes a man down after Bryan Cristante was sent off for two yellow cards, with coach Claudio Ranieri fuming at the final whistle.

Alkmaar 4-1 Galatasaray 

AZ Alkmaar battered Galatasaray 4-1 with Sven Mijnans, Troy Parrott, Jordy Clasie and David Moller Wolfe all on target for the hosts.

Roland Sallai had equalised for Galatasaray who toiled for much of the second half with 10 men after Kaan Ayhan was dismissed.

Ricky Van Wolfswinkel's 95th-minute penalty earned Twente a 2-1 win at home to Bodo/Glimt, while Romania's FCSB won by the same score against PAOK in Greece.
