United legend and pundit Rooney made a scathing assessment of Amorim's tactics on Match of the Day 2 as he also slammed experienced players like Kobbie Mainoo. Taking a cue from Rooney, ex-Liverpool midfielder Danny Murphy said: “It is about intensity, but with wingbacks, different to a back four, it allows you to go and press because you’ve got the extra centre half behind you. But surely that’s what they do in training, no? If you’re a coach of a system – the basics of this system with wingbacks is they press the wide men quick and it doesn’t look like they’re doing it. It’s bizarre for me to see.”
The former English striker then replied: “It’s strange, because that’s why you play a back five with wingbacks. They have to put pressure on the ball or otherwise you get outnumbered in the midfield and the ball comes back into midfield. It was strange, but they had a lot of young players.
"There was a lack of movement and a lack of knowhow on the pitch. They’ve got a 17-year-old lad up front – the youngest ever to start up front for United – and they’re just launching balls up to him. I really felt for Obi today because you can tell he’s inexperienced but it looked like he had no help, they were just throwing balls up to him."
