Manchester United are in great form at the moment, with the players buoyed by their recent EFL Cup win and their triumph over Barcelona in the Europa League.
In contrast, West Ham are having a less successful season, sitting in 16th place in the Premier League. And the away matches of the team are pretty weak - 8 defeats in 12 games. And to be successful in the FA Cup, West Ham do not have as good a bench as Manchester United.
Prediction: Manchester United to win. We recommend the “1 Win” bet, odds 1.66
