Barca's home is very strong, always favorite, and the away is very weak underdog, I will take over 2.5 goals, and barca -2.5
yes Barca too strong play at home, so the other option we have to take a risk by taking a Barca -2.5 or over 3.5 goal to get high odds.
I hope they can make a lot of goals, because their attackers is not yet complete and Neymar has not been able to play for barcelona.
