Fulham boss Martin Jol and captain Brede Hangeland shared the same frustration after the Cottagers' 3-0 defeat at West Ham.
First-half goals from Kevin Nolan, Winston Reid and Matty Taylor were enough to effectively end the game as a contest by the interval at Upton Park.
And the biggest concern for manager and skipper was that Fulham were so troubled by a failure to deal with the Hammers' aerial threat and the subsequent knockdowns from Andy Carroll.
"We expected to have a lot of possession but we did not defend well enough on the things we knew they were good at, so that is something that needs to improve," Hangeland told Fulham's official website.
"It was the worst possible start and we gave ourselves a big mountain to climb; too big.
"We lost the game in the first half and even though we improved in the second half there was too much work to do."
Jol added: "Normally to analyse a team like Chelsea or Manchester United it is difficult but with West Ham it is easier.
"We know that they will play the long ball and look for knockdowns and the first goal is disappointing because we spoke about it, we did not pick up at the end of the first long ball.
"The second goal was a corner kick and the third goal was the same, a big ball and a knockdown and we didn't pick up the second ball."
