Why was Sancho not in the United squad?
This weekend's Spanish friendly double-header, against Atletico Madrid and Rayo Vallecano, will be shown live on the United App, MUTV and ManUtd.com.
“Overnight he got sick, so he is not available,” the Reds boss told MUTV, pre-match.
The skilful Englishman was replaced by Anthony Elanga for the 1-0 defeat against Atletico in Oslo.
Sancho did travel with the squad to Norway, and will be hoping to feature in Sunday’s final pre-season game against Rayo Vallecano at Old Trafford (31 July).
United line-up against Atleti: De Gea; Dalot, Maguire (c), Lindelof, Malacia; McTominay, Fred; Elanga, Fernandes, Rashford; Martial.
