The champion will start this season in Premier League with not a too strong opponent but not too weak as well. They can beat Bournemouth but if they underperform than what they can do best or just usually perform, they will have risk of losing points to Bournemouth. This opponent is able to get points from Liverpool and can punish mistakes from Liverpool.
Personally I am still optimistic that Liverpool will open the league with a perfect victory. However I will not underestimate Bournemouth because this team can be quite troublesome when facing top teams. There is no harm in betting, and I will choose Liverpool for my first bet in the EPL.
