Diogo Dalot's early return to a frozen Carrington on Friday might have elicited a frosty reception from fellow right-back Aaron Wan-Bissaka.
Wan-Bissaka started both of Manchester United's friendlies and might have expected to start against Burnley in the League Cup on Wednesday. Dalot was last seen hobbling off in Al Thumama but this is a right-back who has been available for 69 of United's last 70 games.
Full-back Brandon Williams is available to Erik ten Hag and so is left-back Tyrell Malacia, unused by Netherlands coach Louis van Gaal in Qatar. West Ham are interested in Wan-Bissaka and this is a period where managers remove players from selection if they are intent on a new club in the new year.
