West Ham spend most of their time defending in a low to medium block.
The wingers line up in the central areas of the pitch to possibly push their rivals to the line after passes to the flanks and thus maintain a compact, narrow formation.
The full backs help in the pressing by positioning themselves deeper but come forward to pressure the players entering the half-spaces.
In attack they are keen on ball possession, but tend to adopt a direct approach where they look for the striker and use his ability to collect the ball to then engage players staying closer to goal.
