Silkeborg striker Nicklas Helenius concedes West Ham were a class above for last night's defeat.
West Ham won their Europa Conference League tie 1-0.
Helenius later said: "We are at the level we have. There is a huge difference in level.
"After all, they probably have three or four players who cost more than what Jysk Park costs to build. There must be a difference in level.
"We were disappointed with the first half. We had too little movement and were too weighed down by being in such a place here. The second half was better."
