Billi breaks down all of Tuesday's Matchday 1 matches, before closing out with his Lock. The action begins as 5:45PM GMT, as Arsenal return to Champions League action, priced among the favourites in the outright betting- and for good reason. Injuries dented the Gunners’ chances in last season’s semi-final clash with PSG, but their summer spending has set them up for another deep run in this competition.
The main 8PM clashes see Dortmund travelling to Turin to face Juventus, while Real Madrid begin their campaign at home to Marseille. Juventus have a remarkable record when playing their first Champions League game of the campaign at home, going unbeaten in all 14 occasions that they have started in their own back yard, and they are fancied to make it 15 when they host Juventus on Tuesday.
