The grey haired Toon manager is said to have had a major influence in getting Wadsworth the gig, after taking a phone call from Huddersfield chairman David Taylor.
"Mick is a very solid, very reliable guy who has been in football for a long time," said Sir Bobby yesterday.
"He's no fly-by-night former big-name player who has come in and said: `I've had a great career so now I'm going to be great coach.'
"He has worked his way up from where it matters, and he's equal to any coach in the country."
