Dutch-Ghanaian forward Ernest Poku registered an assist for Besiktas JK, but the Turkish side suffered a dramatic 3-2 defeat to Celtic in the UEFA Europa League.

The encounter at Celtic Park remained goalless at half-time before the action intensified after the break.

Besiktas took the lead in the 54th minute through Junior Olaitan, who converted the rebound after goalkeeper Sam Johnstone had saved his initial penalty.

Celtic responded with two goals from substitutes, as Callum Osmand equalised in the 62nd minute before Camilo Duran put the Scottish side ahead in the 78th minute.

Besiktas refused to give up and restored parity five minutes from time. Poku provided the assist for Orkun Kokcu, who fired a powerful effort into the bottom corner to make it 2-2.

However, Celtic had the final say, with Duran scoring his second goal of the evening in the 87th minute to seal a 3-2 victory for the hosts.

The result handed Besiktas their first defeat in the Europa League league phase this season.

Poku has now registered one goal and one assist in two appearances in the competition.
