Montoya is quite helpful and willing to give advise to a lot of youngsters, so maybe that's a open door for the press or driver's PR to claim Montoya's "support". I wouldn't publish it in my worldwide mag though!
Juan does have a Karting team to support some young drivers. I belive it's looked after by his Brother and over seen by his Father. (fully paid for)
Montoya, a top bloke!
