Arthur has sued Cricket Australia claiming that his sacking smacked of racial bias and that he dealt with a team in which captain Michael Clarke and senior player Shane Watson were constantly at loggerheads.
"Arthur's comments are disappointing, no doubt about it. The issues he is targeting -- racism and what he said about Watto -- those things are pretty poor. And the timing is not flash," McGrath wrote in 'The Guardian'.
McGrath, however, was of the view that the Aussies could turn the situation to their advantage by bouncing back in the ongoing Ashes series which they have started on a losing note.
"...Potentially, it's the sort of situation that could bring the squad together. Sometimes when things are happening outside the team, when forces are at work to try to break the team apart or cause issues, it can actually have a different effect - it can bring the boys closer together. They become more of a unit and they start to protect each other," he explained.
