I once attended a trial with one of the players I recommended and witnessed a funny example of 'the 6ft' african. A senior member of the coaching staff, who was about 5ft 2, walked out and with a list of names. On coming to the african lad he'd named, he turned to the 6ft african, looked up at him and said, "Are you sure your ten!" The lad didn't have time to reply as his mother interrupted with "He ten, he ten" Guess what, despite the obvious birth certificate discrepancies, he was signed!
The thing your ex-utd scout said about not being able to teach football is spot on too, you can't, players are born footballers just that not all get the opportunity to develop their talent.
Are you sure it wasn't an ex City scout you were talking too? ;)
