Martin O'Neill's inspired substitutions saw Celtic come from behind to breathe life into their Europa League campaign with a much-needed 3-2 home victory over Besiktas.

Junior Olaitan's goal - a rebound after Sam Johnstone saved his penalty - looked like condemning Celtic to a fifth consecutive European defeat for the first time in the club's history.

But the introduction of Callum Osmand, Camilo Duran and Colby Donovan just after the hour was a masterstroke from O'Neill.

Osmand fired in the equaliser with his first touch before setting up Duran to round the goalkeeper and put the Hoops ahead.

With five minutes left, Celtic suffered a major blow as Orkun Kokcu came on for Besiktas to fire into the bottom corner from 25 yards.

But Duran was not done. He picked up the ball from Kieran Tierney and poked it into the net two minutes later to restore the Hoops' lead.

Celtic remain in the bottom 12 of the Europa League table, but, with four games left, they still have a chance of reaching the knockout stages.

Remember, remember the fifth of November? It is a night the Celtic fans are unlikely to forget.
