Griffith put Celtic ahead right on half time with a well taken free kick it looked a bit soft free kick and O'Dea looked to have won the ball. Dundee had chances in the first half with Hateley and Holt going close with efforts.
The home side doubled their lead early in the second half. when Bitton scored after Holt had cleared off the line the Celtic player scored from 20 yards. Dundee managed to pull one back with 20 minutes to go. Marcus Haber was played in by O'Hara and the striker's shot was deflected into the net to give the visitors hope.
Dundee kept attacking and should have scored when El Bahktaoui was clean through but somehow put his shot over the bar to the anquist of the Dundee fans.
