We travel to Upton Park on Sunday March 11 to face the side that has grabbed the headlines in the competition so far with away victories over Manchester United and Sunderland.
Meanwhile, we haven’t had to travel outside London to reach the last eight with away wins over Leyton Orient and Charlton and Stockport at home.
Boss George said: “West Ham have very talented individual players and they can take anyone on but we can go there with a lot of confidence.
“There is no reason why we shouldn’t be confident. We’re nine games unbeaten this year and a few weeks ago, when we were getting a bit of criticism for 0-0 draws, it just shows you that they have laid the foundations for this run of form.
“Everyone is nice and positive at the training ground and there is a lot of optimism at the club.”
George Graham says we can go to West Ham full of confidence in the quarter-finals of the FA Cup.
