United haven’t been particularly good this season. There’s uncertainty whether van Gaal will stay or not. West Ham on the other hand have enjoyed a solid campaign, and they’ve been better than recent results suggest. Andy Carroll, who comes into this off the back of scoring a hat-trick against Arsenal, could cause the defensive pairing of Blind and Smalling major problems. Moreover, it’s the last cup game at the Boleyn Ground this season. I definitely see West Ham wrapping it up in 90 minutes, which is available at 2.7 with William Hill.
