Celtic manager Tony Mowbray admitted to huge frustration after a disappointing draw with Rapid Vienna kept his team bottom of Europa League Group C. Scott McDonald's 20th-minute equaliser got Celtic back on track after Stephen McManus's misplaced pass led to Nikica Jelavic's third-minute goal.
But McDonald had a shot cleared off the line and both Shaun Maloney and Gary Caldwell missed great chances as Celtic failed to take advantage of some sustained pressure early in the second half at Parkhead. The draw followed Celtic's late defeat in their opening match at Hapoel Tel Aviv and leaves them with an uphill struggle to qualify for the knockout stages with a double header against Hamburg to come.
"My emotion is frustration," Mowbray said. "We did enough to get three points but didn't score that second goal. We pushed hard but it didn't come. The big frustration is giving them the early goal, knowing the way they play on the counter-attack. It was a very evident individual error. That's football, players make mistakes and you get on with it."
