The four-match ban handed out to Rangers boss Derek McInnes is disproportionate, according to the club's former midfielder Andy Halliday. McInnes described the decision to award Celtic a late penalty at Motherwell in May as "disgusting" while he was still in charge of Hearts. Celtic's 3-2 victory at Fir Park on 13 May kept them one point behind Hearts, who they beat to the title a few days later in a final-day decider.
