Cardiff City have made a formal complaint with the Premier League over the alleged team leaks to Crystal Palace.
The Daily Mail says the Welsh club believe they have concrete evidence that Iain Moody, Palace's director of football who was sacked by Cardiff last year, contacted at least three members of their staff ahead of their fixture earlier this month.
A Premier League statement confirmed they will now investigate. It read: "The Premier League has received a formal complaint from Cardiff City and will now investigate the matter."
