West Ham boss Sam Allardyce remained cautious despite a 2-0 advantage in their play-off semi-final first-leg with Cardiff. Two first-half goals from Jack Collison secured a victory for the Hammers, with the return leg at Upton Park on Monday.
"We need to be as professional on Monday as we were in Cardiff and that should be enough to take us through."
He added: "Two goals is a margin that's difficult for them but they'll be thinking about getting the first goal and whether we'll be nervous and edgy and trying to protect what we've got." "We're not going to get carried away. It was a terrific result but there's a long way to go," Allardyce said.
