Arsenal face Burnley tomorrow in the FA Cup and Alexander recalled the time when he signed for Moyes' Preston: "I told David Moyes my dad Andrew, a lorry driver from Glasgow, was Scottish, because he was asking about my background. He made a joke about getting me into the Scotland squad one day.
"I was 28. You have to take it with a pinch of salt. But three years later - in fact, it was the week after he left for Everton - I was included in the Scotland squad. If it hadn't been for playing under him, I'm sure I wouldn't have got that far. He turned my career around.
"I changed positions from right midfield to right back, then David got hold of me and he was on my case - for about two years and 11 months! But it was just what I needed and I'm eternally grateful to him. He was very hard on me and it took me a long time to realise why he was doing it. I used to fight back against it and we'd have rows. I thought that he was picking on me.
"Then after a year-and-a -half he told me he'd spoken to Craig Brown about getting me in the Scotland squad.
"He said 'That's why I'm always on your case, I know that you can do better.'
"It finally got through that he was doing it for my own good. He made me a better footballer so I owe him a lot."
