Brendan Rodgers has admitted he was experiencing some nerves during Celtic's 4-3 loss to Astana on Tuesday night.

Despite the defeat, the Bhoys advanced to the Champions League group-stage with an 8-4 aggregate victory of the Kazakh side.

Celtic won the first leg 5-0 at Parkhead, but the aggregate become dramatically closer when Astana went ahead 4-1 with twenty minutes left in the match.

The Glasgow giants endured a similar test last season in qualification, edging out Israeli side Hapeol Be'er Shiva 5-4 on aggregate.

"Welcome to the annual Be'er Sheva moment," said the Northern Irishman after the game. "When the second goal went in, that was a good moment for us.

"We turned the momentum of the game then. The players were shocked with the goals we conceded but once we got the second goal the calmness came back into the team and that leads into the third goal and we defended much better then. But I think it is a yearly thing these moments.

"We have gone through this qualification phase really well but we had to withstand that and we have seen it before, teams maybe crumbling away and all of a sudden you have a shock result."
