Celtic's Europa League hopes suffered another blow as they were held to a 1-1 draw at home by historic foes Rapid Vienna.
A misplaced pass from Stephen McManus gifted Nikica Jelavic an early goal but Scott McDonald netted a similar strike in the 20th minute for Celtic, who lost their opening group game against Hapoel Tel Aviv.
McDonald had a shot cleared off the line and both Shaun Maloney and Gary Caldwell missed great chances but Celtic could not sustain their pressure and remain bottom of the group.
After testing Artur Boruc with a decent header from 14 yards moments beforehand, Jelavic raced on to a pass from skipper Steffen Hofmann and rifled an angled shot past the Celtic goalkeeper and into the far corner of the net.
Rapid's apparent desire to simply defend their lead was their downfall in the 20th minute when slack play allowed McDonald to level.
Andreas Dober's careless pass to fellow defender Ragnvald Soma 30 yards from his goal was intercepted by the alert McDonald who raced through to arrow his low drive past Helge Payer from just inside the box.
The visitors stepped up the pace and Hofmann, the lynchpin of Rapid, drove just over from 25 yards and at the other end, on the half-hour mark, Georgios Samaras slid a tantalising pass across the Rapid six-yard box but found no takers.
Celtic were on top but a moment of slackness in the home defence on the hour mark allowed Branko Boskovic to sneak behind them.
However, the midfielder's poor effort from 16 yards trundled harmlessly to Boruc, seconds before Jelavic went down in the Celtic box under pressure from Caldwell, but referee Bruno Paixao waved play on.
The Parkhead side piled forward in the closing stages looking for the winner but too often their passing was frantic rather than controlled and in the end they had to accept the point.
