Celtic boss Brendan Rodgers was delighted with an "outstanding result" after a 1-1 draw against Astana in Kazakhstan.
Defender Yuri Logvinenko headed the home side ahead from a corner in the 19th minute of the Champions League third qualifying round at the noisy Astana Arena, and the Hoops had to withstand some heavy pressure to ensure they only trailed by the one goal.
But, in the 78th minute, striker Leigh Griffiths drilled in a shot from the edge of the box to stun the Kazakhstan champions, a fightback that pleased the former Liverpool manager no end ahead of the second leg next week.
"It was an outstanding result for us. Collectively the mentality was the most pleasing thing," Rodgers said. "I think we were all written off before the game, everyone pretty clear in their opinion of the game, that we would do well to come back with anything other than a loss, but the players deserve an immense amount of credit, to fight and show spirit and passion in the game.
"The resilience and strength that we have built up over the course of the pre-season came into effect.
"I was disappointed with the goal, it is nothing new, but we showed a wonderful mentality to keep fighting and in the second half we restricted them to not so many clear chances and ended up scoring a fantastic goal.
"It is only half-time but [it is] a very important result for us."
Rodgers was also delighted with 20-year-old Irish centre back Eoghan O'Connell, who was making his European debut on a "difficult, unnatural" artificial surface.
"I thought he was outstanding," Rodgers added. "For a young player, he has been on the fringes for a few years, coming into that environment, under pressure, he had very few mistakes in the game.
"You would expect him to make some as a young player but he coped in a very difficult situation."
However, O'Connell was as culpable as any of the Hoops players when Astana scored their goal from a corner and it is an issue the Irishman will address.
"I think there has been an issue there with set-pieces, long before I came in," Rodgers said. "We have lost the man too easy so you put yourself under pressure. Over the course of the pre-season, we defended them well in the main but it is an element that we have to be better at and it is something we will reiterate to the players.
"They had to cope with a long ball, they were quite direct at times and a high percentage of times we dealt quite well with it but we need to ensure that our concentration is 100 per cent."
