The Hammers battled their way to a goalless draw at Liverpool last weekend when there were plenty of questions asked about the system and style of play deployed by boss Sam Allardyce.
However, Pochettino says his players must respect West Ham's approach if they are to claim the three points.
"There are always different tastes and different points of view in football," he said.
"I think they got a result that was positive for them [against Liverpool]. Many people are interested in how you win and how you get positive results and there are some that don't care about that, both points of view are respected.
"I think West Ham are going to be very direct, very aggressive and play the long ball to try and keep us in our half.
"There were many times during the game against Liverpool when this was effective for them - we have to take into account that their players are very tall and aggressive, very physical.
"We have to try and impose our brand of football, be dynamic and keep going forward. We also need to be aware that we will suffer against them when we don't have the ball."
