Celtic face a tricky test against Slavia Prague in the Champions League play-off should they progress past CFR Cluj in the third qualifying round.
Of the unseeded sides in the pot for either Celtic or Cluj to face in the final round before the Champions League group stage, Slavia were arguably one of, if not the most difficult side, given their exploits in Europe last season.
The side from the Czech Republic reached the quarter finals of the Europa League, seeing off Zenit St. Petersburg, Bordeaux and FC Copenhagen in the group, before beating both Genk and Sevilla in the knockout stages.
Eventual Europa League winners Chelsea were their opponents in the quarters, and Slavia proved they were no pushovers against the Premier League giants, scoring three goals at Stamford Bridge in a 4-3 second leg defeat, after a 1-0 win for the Blues in the Czech Republic.
