All five British representatives in this year's Champions League have tough encounters to negotiate on matchday two of the competition.
And the most difficult is the one Celtic face when they go head-to-head with Barcelona at Celtic Park.
Celtic defeated the Catalans 2-1 in a memorable tie last November, and a repeat of that win is priced at 20/1. However, Barcelona have won all seven of their La Liga fixtures and have almost been playing in second gear.
Despite not having Lionel Messi fit, Barca are 2/5 to win in Scotland and should have no problems in securing the victory given their form. A 3-1 win to Barcelona at 10/1 is our pick of the bets.
