Ghanaian forward Richmond Boakye fired Red Star ahead in Copenhagen and Dame N'Doye levelled to force the shootout in which the Danish champions missed two chances to progress before they were dumped out by visiting keeper Milan Borjan.

Having earned a 1-1 draw in Romania, Celtic rallied from an early deficit to lead 3-2 before a late collapse gifted Cluj two late goals and a 5-4 aggregate win over the 1967 European champions.

Billel Ormani scored for Cluj after they trailed 2-1 and 3-2 and George Tucudean delivered the final blow in stoppage time as Celtic threw men forward.

Porto fell 3-0 behind to Krasnodar in a dire first half for the Portuguese side as Magomed Suleymanov struck twice after Tonny Vilhena had levelled the tie on aggregate.
