Don't worry, you will surely see the pair of Lionel Messi and Griezmann upfront alongside Suarez as these three are preferred starting trio for Barcelona since Dembele is injured.
I won't deny the fact that adding semi-finals to Supercopa have added some spices to the competition. Earlier only single match (or 2 legs sometimes) was/were used to play but now contest has been extended to 4 best Spanish sides, great!
Odds for Barcelona's win are almost 2/1 and worth a try. I am thinking to go 4/5th amount on Barca's win while 1/5th on draw which is around 18/5.
