Erik ten Hag has admitted he is worried about the defensive capability of his Manchester United side following their pre-season tour of the United States.
The Red Devils played three games in the United States, losing to Arsenal and Liverpool either side of a victory against La Liga side Real Betis.
Even in the latter, United failed to convince defensively and across the trio of matches combined, conceded seven goals.
Ten Hag is now out of time to run any more experiments with his side...
