But this time his anger was firmly directed at the majority of his players.
He added: "We didn't play as I wanted them to play; we didn't play as I prepared the team to play".
United ran out 2-0 winners over their fellow Premier League side at Old Trafford on Saturday evening, with Romelu Lukaku and Nemanja Matic finding the net. I had the reaction from some of them. And because some of them were mentally strong enough and with football quality to play was the reason why we won.
Mourinho showed particular anger that his demand in training for a quicker and more incisive transition game had not been carried out in practice. "The biggest frustration for me is when I work on the pitch and I see contradictions in the match", he continued.
And the Special One has now laid bare his thoughts on Shaw's performance, with the England global most likely facing another spell out of the side as a result. "So, I don't want the fans to have lower expectations, I want the fans to have high expectations because I want the players to have high expectations too".
The Portuguese has been trying to get the Brazilian to switch alliance from London to Manchester, and after failed attempts last summer, he is said to resume his pursuit of the Chelsea forward.
As well as Matic, Mourinho praised young midfielder Scott McTominay, although even those words were peppered with criticism of others.
But they produced a response against Brighton and Hove Albion, putting in a controlled - yet albeit meek at times - performance to claim a 2-0 win and book a trip to Wembley, with Matic claiming a goal and an assist.
