Speaking to the East Anglian Daily Times the former Everton boss said: "It would be handy if we could do what I have done with another team against West Ham in a two-legged semi-final though I doubt if it will be 6-0 again.
"It doesn't matter if it is 1-0 or 5-4 just as long as we go there with a lead and we come out on top again. We know we can score goals from anywhere in the side and although we did not play well against Cardiff I felt defensively we did do well.
"That has gone now and the players can relax a little, though not too much. We only know the gung-ho way of playing but West Ham have quality strikers as well in Marlon Harewood, Bobby Zamora and David Connolly, with Brian Deane to come off the bench, so we will have to be wary of that."
