"Scott is flattered by the interest of Wigan and Roberto Martinez, but the prospect of leaving Celtic on-loan is not something he is keen on," Sticca told tribalfootball.com.
"Scott is settled at Celtic, where he's enjoyed an outstanding two seasons under Gordon Strachan and is looking forward to a third with Tony Mowbray. Scott has told me he's excited about the plans Mowbray has and is desperate to bring the SPL title back to the club."
McDonald is already amongst the goals at home and in Europe for Celtic and he knows being established with the Hoops is his best chance of shining in his first World Cup next year.
"Scott was gutted to miss the 2006 World Cup and is determined to give himself every chance of enjoying a successful one next year," added Sticca. "So, the prospect of angling for a move away from Celtic is a non-starter. He wants to stay."
