Inter Milan president Steven Zhang said on Saturday that the Serie A champions' financial stability was being threatened by investment fund Oaktree as owners Suning scrambled to repay a debt of nearly 400 million euros.Suning could cede control of the club if they don't make good on their debt and Zhang, who hasn't been to Italy for months and lost a court case with China Construction Bank over personal debts of 320 million euros, claimed that Oaktree had been actively obstructing negotiations.
