Before the 36-team league phase kicks off, 52 clubs have to win their way in through a summer of Champions League qualifiers, played out over two legs between clubs you might not know yet and a few you definitely do.
For the champions of Europe's smaller leagues it is the only route to the top table. For bigger names who slipped up at home, it is a nervy detour they would rather avoid. Either way, it all starts on 7 July.
Odds are live now, so you can back every qualifying tie on our Champions League betting page.
