Spanish giants FC Barcelona begin their UEFA Champions League campaign on Tuesday when they welcome Scottish outfit Celtic to the Camp Nou, while Paris Saint-Germain play host to Arsenal in Paris – here are the starting line-ups.
The Catalan club will want to make amends for their 2-1 loss to La Liga newcomers Alaves on Saturday evening.
Celtic will travel to Barcelona with some confidence after they hammered city rivals Rangers 5-1 at home this past weekend.
The Blaugrana have a good record against the Scottish side in the Champions League, having won five out of their past six encounters, and only losing two of the two sides' previous 10 meetings.
Brendan Rodger's men travel to Spain with a massive winless streak, however – Celtic have not won in their past 14 matches against La Liga opposition, so the odds are heavily stacked against them.
Lionel Messi and Luis Suarez will be backed to be one of the competition's highest goalscorers this season, but keep your eye on Moussa Dembele as he may sneak a goal or two in Tuesday's encounter. (Marshalls' odds: Messi to score at 1.3) (Marshalls' odds: Dembele to score at 6)
Here are the starting line-ups:
Barcelona: Ter Stegen; Roberto, Pique, Umtiti, Alba; Busquets, Rakitic, Gomes; Messi, Neymar, Suarez
Celtic: De Vries; Gamboa, Lustig, Sviatchenko, Toure, Tierney; Bitton, Brown, Roberts; Sinclair, Dembele
PSG vs Arsenal
In the other big game of the evening, English side Arsenal will face Ligue 1 champions Paris Saint-Germain.
This is the 19th consecutive season the Gunners are in the group stage of the Champions League, but go into this tie having lost two of their past three away games in this competition.
