Beardo insists Carrick can make the difference in South Africa.
Beardsley told the Evening Chronicle: "It's brilliant to have a Geordie in there.
"I was 100% sure he would get in and I never had any doubt in him. He's not at Newcastle but Newcastle can't get them all. Sadly he went to West Ham but people develop at different times and different ages.
"As I say you can't get them all.
"Alan Shearer had to start his career away from Newcastle and so did I.
"Michael did too, but you have to hold your hands up and say he's a great player."
