Erik ten Hag labelled Manchester United's first-half performance against Leicester as "rubbish".
United were fortunate to lead 1-0 at half-time through Marcus Rashford's clinical 25th-minute strike after Harvey Barnes and Kelechi Iheanacho were brilliantly denied by David de Gea with the game goalless.
Rashford was played onside by Leicester centre-back Harry Souttar from Bruno Fernandes's perceptive pass and Ten Hag claimed only those two pieces of play were exempt from criticism.
