BBC Scotland's senior football reporter at Celtic Park
"The former Celtic manager Neil Lennon used to describe this match - the second leg of the Champions League play-off - as the biggest game of the season and it's a sentiment that makes sense.
"The financial boost from qualifying for the group stage is massive - £14m or thereabouts for Celtic last year. Just as importantly, it keeps a level of excitement around the Scottish game that the domestic scene just can't match."
