The only way I would be playing O'Donnell in terms of giving the guy a chance would be to change formation to a 3-5-2 (0r 5-3-2) dependant on attack/defence.
Kelly
Sondre, Ojala, Mugabi
O'Donnell, Slattery, Goss, Donnelly, Carroll,
Watt, Van Veen
Accomodating this make us more solid in midfield - but completely lacks width. Would be dull and not much fun, but may get results.
