Tony Mowbray claimed his side's dramatic Europa League comeback to draw 3-3 against Rapid Vienna in the Ernst Happel Stadium epitomised the spirit of the Parkhead club.
An experimental Hoops side with seven changes from last weekend's win over Motherwell found themselves three goals behind after only 19 minutes. However, Celtic refused to buckle completely and began a thrilling comeback when Marc-Antoine Fortune scored before the break.
The former Nancy frontman doubled his tally in the 67th minute before Paul McGowan, making his first start of the season, drove in a stoppage-time leveller to keep Celtic in third place.
"I didn't learn anything about the players that I didn't know," Mowbray said.
"The last 80 minutes epitomises our club. We needed to react and be positive in adversity and we did just that. We showed what our spirit was all about.
"The players' desire to get back in to the game and really, the Celtic spirit, was there to be seen.
"We kept playing football and creating chances and worked our way back into the game.
"We ultimately got some reward but the players are disappointed that we didn't score a few more goals."
He added: "The start to the game was down to a combination of things. They had some very good players and we played in the wrong areas of the pitch for the first few minutes.
"We should have been more direct but we brought trouble on ourselves and they took advantage of it.
"We talked before the game how we would be positive and obviously the first 10 minutes were not what we wanted but I prefer to talk about the next 80."
