West Ham boss Sam Allardyce admits his side are far happier on their Championship travels at the moment than they are playing at Upton Park.
Away from their East London home they have registered three wins, scoring four twice including Sunday's 4-1 success at Nottingham Forest.
Allardyce said: "We scored four again. It's a very unusual victory. At the second time of asking we went away and scored four. To repeat it immediately is outstanding.
"It was an outstanding performance and showed a commitment to overcome a difficult team at a difficult ground. We punished them with our quality in the final third and took full advantage of the excellent delivery of the ball into the box.
"At Upton Park there's too much anxiety, we're feeling more comfortable away from home. It's understandable with some of the players' memories of last season. But that's three away victories on the trot."
