Genuine,
The problem over here is that the Champions League matches kick off at 1.45am (7.45pm British time).
The bars tend to close at 1am.However the games will be screened live on Thai TV.Last night United were on Channel 7 and Arsenal on Channel 3 so you should have no problem watching both games but probably on TV in your room and stock up on the Beer Changs from 7/11 beforehand.
Maybe one of the farang bars might have a lock in to 4am,when the game finishes,so one of the other posters might know.
PS:Great result for United last night but dont know why he brought Nani on.Porto gained the initiative after that but its the result that counts and should be two classics against Arsenal !
