"Our first home win is imperative," he said. "We fell flat on our face against City and against Wigan had to claw our way back, while away from home it's been different. We need to win our first home game and that's what we'll be stressing.
"The onus is on us at Upton Park, and we need to stress that as well. We may have to be patient and break teams down, but that's only what the majority of the Premiership teams have to do at home.
"Perhaps the opposition approach is different. We had a great run last year and maybe one or two are now coming safety first, and it's up to us to break that down.
"Near the end of last season we had teams on the back foot from the first minute, and we haven't had that oomph yet. We're not lacking anything, but it was just a bit flat.
"When you're at home it's down to you to make the away team know you're at home, and we haven't done that yet. Early on at Birmingham and Reading we knew we were away from home, but I don't think Manchester City and Wigan did."
