Our skipper netted a first-half penalty before curling in a sublime effort in the second period, with these goals proving to be enough to edge the Hammers in the match at the MetLife Stadium.
Bruno played in an advanced midfield role, alongside Matheus Cunha, and the duo linked up well during a first half where Ruben Amorim's men imposed ourselves on West Ham.
After frantic early stages which featured Rasmus Hojlund hitting the post following a Fernandes pass, Alphonse Areola took down Ayden Heaven in the box.
Bruno converted the penalty and after half-time, took our lead to two.
