CELTIC'S players suffered a triple whammy in Giurgiu last night.

Wham ... they lost a late equaliser to Astra.

Thump ... they had what looked like a perfectly good winner from Leigh Griffiths disallowed for an alleged push on a defender.

Wallop ... they came off the pitch to discover that Salzburg had hammered Dinamo in Zagreb.

That meant that if they had held on to their lead against Astra, they would have joined the Austrians in securing qualification to the last 32.

It left the Hoops dressing-room gutted, but Ronny Deila's men have vowed to bounce back from the bitter disappointment and get the job done when Salzburg come to Glasgow on November 27.

The Hoops still hold second spot in the group, and need just two more points to fend off the challenge from their final-day opponents Dinamo.

Callum McGregor revealed they want to have everything sewn up before they head for Zagreb on December 11.

He said: "We remain unbeaten in the group and still have two chances to get through. We need two points, and it is definitely doable with the form we have shown so far.

"We will all be focused on trying to get it done as soon as possible, so that means the Salzburg game in a few weeks."

McGregor can't hide the pain which comes from the fact they could already be in the draw for the last 32.

"What makes us so disappointed is that we created a lot of chances and perhaps we should have put the game to bed earlier," he said. "That is something we need to learn to do, though we are getting better as we have scored a lot of goals in recent games.

"We are getting towards it. But when you play in European games you need to be ruthless.

"Although we played well and got a decent result, it still feels like a defeat. It was hard to take when they scored late on. Then we have one disallowed and you hear the result in the other game.

"We thought Leigh had done it for us. It was delayed reaction from the referee. We are all disappointed about that, but sometimes you get them, and sometimes you don't."

McGregor, like the rest of the squad, was happy the game went ahead after serious concern it would be postponed until today due to fog.

He said: "We just had to prepare as normal, and believe it would be on. Everyone did that, and Scott Brown made sure we were all motivated.

"We knew in our heads that we had to play the game, regardless of if it was last night or delayed until today.

"The conditions didn't affect us during the game. Obviously it was foggy before kick off. But the more you played in it, the more your eyes adjusted."
