Sam Allardyce wants West Ham to build on Saturday's 2-1 derby win over Millwall and stretch their lead at the top of the Championship.

The Hammers are four points clear after bouncing back from Tuesday's 5-1 drubbing at Ipswich with victory over their fierce rivals despite having captain Kevin Nolan sent off early on.

"We've got to continue to understand there are no easy games in this division and we played an Ipswich side that tore us to bits on occasions," said Upton Park boss Allardyce.

"If you allow complacency to slip in you'll see what you get as we did at Ipswich.

"Every time apart from once this season when we've had a hiccup we've bounced back.

"Doing it under the circumstances we were faced with on Saturday should help us kick on from here and it was a fantastic result and a fantastic three points."
