Celtic completed a clean sweep of domestic trophies this season but when they return from their summer break eyes will turn to Europe once again.

Brendan Rodgers' side enjoyed big European nights against Barcelona, Manchester City and Borussia Monchengladbach last time and that's only whetted the appetite for another crack at the group stage and Europe's best sides.

It's a long road to that point though, and Celtic have a few hurdles to overcome.

Entering at the second qualifying round, Celtic's co-efficient of 42.785 will guarantee that they are seeded throughout qualification

Celtic's UEFA co-efficient ranking, the highest of any team in the second qualifying round, will guarantee that they can't draw the likes of BATE Borisov, Legia Warsaw, FC Copenhagen or Red Bull Salzburg but as last season proved even Europe's minnows can spring a surprise on any given day.

The Scottish champions can draw one of 17 teams at this stage.

Five of the sides will be those who progress from the first qualifying round. The draw for that round also takes place on June 19 and involves Welsh side The New Saints, Northern Irish champions Linfield, Faroe Islands league winners Vikingur, Hibernians of Malta, Andorra's FC Santa Coloma or the champions of San Marino, Armenia, Andorra, Estonia or Kosovo.

The remaining 12 possible opponents for Celtic are already confirmed.

Highest ranked are Slovak champions MSK Zilina, who won their 30-game league by 17 points this season. Lithuanian league winner Zalgiris Vilnius and Irish champions Dundalk are also in the pot along with Macedonia's Vardar and Luxembourg's Dudelange.

Albania's Kukesi will be in the Champions League qualifiers for the first time or Celtic could face Slovak side Zrinjski Mostar, who were knocked out by Legia Warsaw in the second round last season.

Montenegran champions FK Buducnost Podgorica are in the draw, as are Hungary's Honved, Finnish representatives IFK Mariehamm, Latvian league winners Spartaks Jurmala or Georgia's Samtredia.
