"There was something that happened in that game yesterday that I mentioned on my podcast two or three weeks ago that I said we couldn't see again... when you're putting Mason Mount at left wing-back and he's ended up at left wing-back again yesterday in the last five minutes to the game, it starts to look awful," Neville said.
"Ruben Amorim’s had a pre-season. He's had a week now in between each of his games nearly or most of the weeks because Manchester United aren't in Europe. Yet, the performances are as poor as ever. The results are catastrophic really in Manchester United terms.
"You can't put Mason Mount at left wing-back. I'm sorry, it just can't happen. I can't… I can't watch Mason Mount play left wing back in a football team. I struggle at times to watch him in in his position, but actually putting him out there on the left wing is just or left wing back is ridiculous, absolutely ridiculous.
"The manager's obviously a good coach. He's had a great record in Portugal, but it's not clicking at all. It's not clicking. And the thing is for me, when I said just before, maybe I didn't finish what I was going to say, but it looked to me like I said, the players and the ideas are not connecting at all.

"The other thing that I've said, and I said it under [Erik] ten Hag towards the end, he keeps changing his back four. That's what I used to say under Ten Hag. He didn't play with the back five. Kept changing his back four, his centre-backs... You cannot continually keep changing your back three and back five. It's impossible. I mean, that is the sort of part of the pitch where you need reliability and you need continuity to build relationships."
