I'm also of the opinion that Arsenal will beat West Ham United and therefore reduce the deficit from 8 points to 5 points, I'm really positive about that. I just hope Liverpool doesn't start feeling the pressure because they really need to be composed of they are to win the EPL this season.
A really tough game is all that I can anticipate, I know the gunners are at the position where they appear really tough and strong especially as they are even aiming at the league title too just like almost all other top four team but then westham isn't a team to undermine not for any reason as they have been really of a top for and have a relatively fair average performance that is getting them some very productive results that appears like they are in a very good form and I believe even if they get to loose against Arsenal it will be with a slim margin.
West Ham isn't a team to undermine no doubt but I don't think they've shown enough strength that should make you think they'll be able to get a result against Arsenal at the Emirates stadium. Arsenal manager and players still believes that they stand a very good chance of catching up with Liverpool at the top of the English Premier League table and playing at home against a struggling West Ham side that are currently in the 16th position of the league table, I don't expect Arsenal to drop a single point in that game.
Neither do I expect Arsenal to drop points in this particular match. Arsenal have been patiently waiting for Liverpool to drop points in their two matches they have this week. They got what they wanted in the first one, as Liverpool dropped against Aston villa. Now they Arsenal have to respond and will to close the gap. If they now mess up and drop points against Westham, then people will see them as not being serious, the points Liverpool had dropped against Villa won't benefit them in any way. The Emirates stadium will be very hot for Westham united. Because I see a situation where Arsenal will start scoring from the first half till the end. Arsenal will use them and send a message to Liverpool that they are read for the title race. Arsenal will score up to 4 goals and above in this particular match.
