West Ham vs Arsenal prediction (Over/Under)

Arsenal sit fifth place in the table and play against West Ham who are tenth (midtable). Arsenal have had two matches under 2.5 out of their last six while West Ham have had four under 2.5 matches out of last six. H2H says two out of last four games played have been under. We did not have league games past weekend and so this should have given the players proper rest as in Cup matches,the first eleven of most teams changes in order to give rest to most players who regularly play. West Ham would be strong defensively and won't let Arsenal score many goals past them. I strongly feel that this match will be under 2.5 goals.
