if you choose chelsea +0.5 means we expect a draw, so better choose under 3.5 goals but little odd just 1.27, but suitable for making parlay 
Most Chelsea's match in the last season against a top tier team usually ended up with them being the winner or a draw because they will use a heavy defensive strategy so +0.5 is pretty much not a bad choice.
Liverpool vs AFC Bournemouth, liverpool win
Pretty much risky. I'd say to stay away from every liverpool's match for the time being as they have not shown any of their quality yet . Their last match was pretty much a win because the goddess of luck was on their side.
But it could end with a 2-2 draw
It wont happen. City is currently on their top form but Chelsea is pretty much still struggling to find their best performance. Their previous match shows the difference of this both team and there will be only two scenario, either Manchester City come out as a winner or Chelsea miraculously pull out a goal or two to make it a draw
I read this 3 times and couldn't figure out what you just said mate sorry
