I think in the upcoming match West Ham has a chance to get three points. Moyes' team has an excellent form, plays at home and has no serious problems with the squad. Brighton is a strong and played team, but recently the Seagulls have often lost points. Although in the last round Brighton managed to inflict a defeat on Tottenham. So West Ham is waiting for a tough game.
I think Brighton also have some good players. Hammers on other hand are also a tough team. I think both are on equal terms. If we take performance into consideration then obviously West Ham are performing better but make no mistake of undermining Brighton at all because they had crazy last season and are capable of big things for example the last game win against Spurs with 4-2 scoreline. Its hard to pick a winner but I expect both teams to score in this match.
