Tottenham have missed out on top spot in their Europa League group after losing 1 - 0 at Turkish side Besiktas in a game which was twice suspended due to floodlight failure.
Both sides are through to the last-32, but Spurs finish second in Group C.
The match in Istanbul was halted in the first half and again in second half stoppage time on both occasions the players were taken off the pitch.
Cenk Tosun scored the only goal of the game for Besiktas.
Meanwhile, Celtic were already through as Group D runners-up before their 4 - 3 defeat at Dinamo Zagreb.
The Hoops' goals came from Kris Commons, Stefan Scepovic, and a Pivaric own goal, while Marko Pjaca scored a hat-trick for the Croatian side.
