CELTIC RATINGS: Star turns emerge from the bench to save the day but how many of Martin O'Neill's starting XI earned pass marks? Very few...

Substitutes Callum Osmand and Camilo Duran sparked Celtic into life as the Scottish champions got off the mark in the Europa League in a 3-2 victory over Besiktas. Martin O’Neill’s side were heading for a seventh defeat in 11 matches and bottom place when Junior Olaitan netted on the rebound after Sam Johnstone had saved his 54th-minute penalty. But Osmand drilled home the equaliser with his first touch in the 62nd minute, seconds after coming off the bench in a triple change, and the 20-year-old set up Duran to put the hosts in front.
