West Ham have netted 11 goals in their last three games in all competitions, with Carlton Cole and new loan signing Demba Ba scoring the lion's share. But Lars Jacobsen admits their Barclays Premier League survival hopes may now rest on keeping goals out at the other end.

"It seems like we're able to score now. We just need to keep a clean sheet," said right-back Jacobsen.
