Di Canioâ€™s style in charge at Swindon was described as â€śmanagement by hand grenadeâ€ť by former Robins chief Nick Watkins.
But former Manchester United defender Oâ€™Shea, 31, said: â€śItâ€™s not a wacky world. Iâ€™ve been in football a long time and first and foremost the manager is just wanting to do his best for Sunderland.
â€śWeâ€™re doing a lot of work without the ball, with shape and pattern. And that is similar to what we did with Alex Ferguson.â€ť
