Real Madrid have reported Inter Milan to FIFA over an alleged illegal approach for midfielder Luka Modric.
The 32-year-old Croat, who captained his country to the World Cup final and was named player of the tournament, has been linked with a move to Serie A.
Real president Florentino Perez said earlier this month the only way Modric would leave was if his 750 million euro (£671m) release clause was met.
The Spanish giants sold Cristiano Ronaldo to Juventus for £99.2m.
Modric joined Real from Tottenham in 2012 and has won La Liga once and the Champions League four times.
