Ruben Amorim still hopes Bryan Mbeumo will be able to make his Manchester United debut on the club's summer tour of the US after missing the win over West Ham at MetLife Stadium in New Jersey.
Mbeumo completed his £71million move from Brentford just in time to join United's three-match trip to America.
But he was too far behind in his pre-season preparations to feature in the opening game of the Premier League Summer Series as two goals from captain Bruno Fernandes gave Amorim's side victory over the Hammers.
