Barcelona kick off their Champions League campaign against Scottish giants Celtic in Group C hoping to extend their 11 game win streak at the Camp Nou.
The fact that Alaves managed to beat Barcelona 2-1 at home will give Celtic some optimism but the La Liga giants will welcome back Neymar and Lionel Messi as well as Luis Suarez are both fit.
Turkish international winger Arda Turan is fit but will not start as Neymar has returned and will play in the position he has occupied in the Brazilian’s absence.
Celtic will enter the game in high spirits after beating arch-rivals Rangers 5-1 in the Old Firm derby.
Moussa Dembélé’s hat-trick was the first for Celtic against Rangers in the league since Stevie Chalmers in 1966.
Celtic will be without Griffiths but derby hero Dembele is fit and will start for the Bhoys.
