Lineker called Ferguson the same thing on air during last season but Ferguson, who refuses to give interviews to the BBC, has responded to the former England striker's comments.
Biting back: Manchester United manager Alex Ferguson was less than impressed by Gary Lineker's comments.
Ferguson said: “Gary Lineker, a bright boy from the BBC, says I’m childish.
“Well, he should know about that himself.
"He has been subjected to a lot of stuff in the media and I know he tried to have stuff stopped from getting in newspapers from time to time.
“So he’ll understand what childishness means, because he is childish. I don’t think I’m childish at all.”
