Celtic goalkeeper Artur Boruc played down his late penalty save after the Bhoys beat Manchester United 1-0 to qualify for the knockout stages of the Champions League.
The Poland international denied Louis Saha a minute from time at Parkhead, sending the runaway SPL leaders into the last 16 of Europe's elite club competition.
Boruc had been beaten from the spot by Saha in the 3-2 reverse at Old Trafford earlier on this season and learned from that event to deny the France striker second time around.
He said: "I don't know about it being a great save from the penalty. Every time a keeper saves a penalty it's luck, that's all.
"I was thinking about the last penalty he scored against me and I thought he might do the same thing, that's what was on my mind.
"We were celebrating in the dressing room when someone came in with the news that we had qualified, so there was a double celebration."
