Gary Neville says that Manchester Utd have reached a new low and are drained of all confidence after a humiliating 4-0 defeat to Brentford

Gary said he couldn't play at centre-back due to his height.

It took me back when I heard he was 5 feet 9in. I played center-back in the youth and reserve teams.

In my first 150 games, I played about 40 or 50 games at centre-back, and I'd seen PaulParker before me who was an outstanding center-back.

He had to put me at right-back because I couldn't handle the 6ft 2in strikers that were up against me in the box on set pieces.

Manchester United manager Erik ten Hag says his players didn't play with belief or responsibility in the defeat to Brentford

I thought I was a decent centre-back when I was younger because I knew my position. Gary had to swap with me, so I couldn't do it.

It reminded me of Pally who used to swap with me when I saw him.

It's not good to have to swap positions at centre-back to make up for the other one. In the first half, they targeted him.
