"The one standout is a left armer, whose hero is Allan Donald - you can tell by the way he follows through, a mirror image of AD.
"His name is Neil Wagenaar and he'll be someone to look out for it the future."
Despite the incorrect spelling, McGrath was indeed referring to current Black Caps player Neil Wagner, who is currently ranked the world's second best Test bowler behind Australia's Pat Cummins.
Wagner migrated to New Zealand in 2008 to pursue a career in cricket, and made his Test debut four years later. Since then, the firey left-armer has taken 204 Test wickets at a stellar average of 26.63 - better than any other fulltime Kiwi bowler over the same period.
He is currently the seventh highest wicket-taker for New Zealand in Test history, quickly closing in on Chris Cairns and Chris Martin.
The 33-year-old was also New Zealand's highest wicket-taker during the recent Trans Tasman series, where he claimed 17 scalps at 22.76. He has dismissed Steve Smith - the best since Bradman - five times in four Test matches.
Wagner had no idea McGrath had made those comments about his bowling in 2003, and thought it was "amazing" the cricket great even remembered him.
"Didn't know this! Amazing and extremely kind!" Wagner posted on Twitter.
"Remember how awesome @glennmcgrath11 @BrettLee_58 was! Carried my bag back to my parents car! Feels like yesterday!
"Pretty awesome memory and so cool to see them both a month ago in the middle of the SCG!"
Wagner featured in the recent SCG New Year's Pink Test, where he handed McGrath a signed cap in support of breast cancer research.
New Zealand face cricket giants India in a two-Test series later this month, starting on Friday, 21st February in Wellington.
