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.
Arsenal should not give up points at the moment to keep up with Liverpool. Therefore, it is very important to collect three points against West Ham in today's match. If Arsenal can attack strongly, they will definitely win at home.
Moreover, West Ham is currently at the bottom of the points table, so no matter how much they attack, they may not be able to break Arsenal in any way. However, Arsenal's defense is very good and their strong attack line is also excellent. In that case, if Arsenal can win today's match, their point gap with Liverpool in the points table will be reduced a lot.
