Tottenham's Heung-Ming Son will undergo surgery on Friday.
The South Korea international fractured his right forearm during the Red Devils 3-2 loss to Qatar on Tuesday.
The 24-year old were substituted after 34 minutes following an incident in which he landed awkwardly after an aerial collision with Qatar's Mohammad Musa.
Son scored 5 goals for Spurs during their nine-match winning streak in the final third of the season, and bagged 21 in total for the season.
