Luka Jovic scored against his parent club Benfica to get Frankfurt level on the scoresheet.
Ruben Dias scored for Benfica and his goal was sandwiched between two goals from Felix as Benfica led 4-1 with more than half hour left to play. Goncalo Paciencia scored an important away goal to give his side some relief.
In an all Spanish affair, Valencia beat Villarreal 3-1 with a Goncalo Guedes brace making up for a penalty miss from Dani Parejo.
In the 6th minute, Guedes was tripped in the penalty box and Dani Parejo stepped up to take the penalty. While Parejo missed, Guedes slotted home from close range to give Valencia the lead.
