It's so sympathetic to see that you also had this option picked as well, usually we have known Arsenal to be a leading team and i picked over 2.5 as well with the hope the match would end that way, judging from their past matches.
Most times i also have that feelings but what i just said to myself is never to have anything attached to my mind that could affect me or break me down because we already that gambling is a game or uncertainty and anything might happened since we can't see the future of what they gonna play then any results of what they have already determined to play and we can't change it for any reason.
