I think a lot has to lose on Arsenal betting. Yes, it becomes natural that the trust in Arsenal is higher than Manchester United. They are a team that has yet to swallow defeat coupled with consistent performances.
Yes, the debut of Manchester United's expensive player contributed to the goal for Manchester United's victory. It's a good start, but of course we can't see just this game.
Mist prediction site go for Manchester bUnited to win. Because it is away match for Arsenal while Manchester United is improving, some people will not go for Arsenal. Some people see good potential that both team would score. There are tyos of other selection in bookmakers that are not 1x2 which some people can still win. I thought Arsenal may win though, but I went for both team to score which later favoured me. Nobody can be able to accurately predict that kind of match.
