West Ham has a pretty good performance at the moment and I think they will definitely be targeting a win when they play against Luton. Maybe it won't be easy for West Ham to beat Luton because even though Luton has never even won a victory but this time they will play at home, so it is very likely that they will give West Ham all-out resistance.
The first half is almost over, West Ham is 0-1 ahead of their opponents and they are sure to keep it. From the strategy and game statistics, West Ham will most likely be able to double the goals and seal victory in this away match, but you are right that Luton Town will probably give their best in the home match.
West Ham's performance was certainly surprising, but I expect their first defeat in the mid-month match against Manchester City. Even though West Ham will be playing at home, they are not the team that will be the favorite to win. Once again, I'm expecting West Ham's first defeat on matchday 5 of the month.
