19-year-old Wabara was due at Reseheath this morning after a deal to bring the England U-19 player on loan had been agreed with Manchester City's David Platt and Brian Marwood.
Gradi told the press "He decided not to come. I think his agent decided he is too good to play in this league, and I am not going to start arguing with agents.
"Everything was done. Platty and Brian Marwood had been very helpful and the vibes were the player was willing to come."
