No less a judge than Wladimir Klitschko, holder of three versions of the world heavyweight title, is taking an interest in the unbeaten 6ft 7in 26-year-old, while the English duo of David Haye and Dereck Chisora are also vying for his services, according to the boxer's manager, Tommy Gilmour.
Cornish has a height advantage over all three and Chisora and Haye are especially keen to spar with the giant Scot ahead of their forthcoming championship bouts against Edmund Gerber and Tyson Fury respectively.
Gilmour said: "Gary sparred with Chisora prior to turning pro, but now, with the experience he's gained, he will be able to handle himself much better. Haye also remains a distinct possibility. I have spoken with his manager, Adam Booth, and he says that Haye is keen to spar with Gary, given that Fury is 6ft 9in, and he wants a boxer of similar height so he can get used to fighting someone taller.
"Klitschko has also sounded us out concerning Gary's availability and that's a clear indication that people are starting to notice him. We can't afford to lose sight of the fact that Gary is still something of a novice, given that he had only nine bouts as an amateur, but anyone who remains undefeated after 15 fights deserves credit."
Cornish will be the main support on promoter Frank Warren's annual charity show at London's Hilton Hotel a week tomorrow and Gilmour added: "It will be further exposure for Gary on Sky and, hopefully it'll open more doors.
"If Gary looks good in this one, we will put him out again in November on another TV show and also before Christmas, with the possibility of a trip to America to train in between."
