Real Madrid president Florentino Perez plans to make a stark warning to Atletico counterpart Enrique Cerezo tonight.
Ahead of tonight's Champions League semifinal first-leg, the two presidents will meet where Perez will raise Real's interest in Theo Hernandez.
Both Real and Barcelona are chasing the fullback, currently on-loan at Alaves.
Don Balon says Perez wants assurances from Cerezo that Atletico will do all they can to prevent Theo from joining Barca.
And if Cerezo refuses, Perez will insist their 'non-aggression' pact is over and Real will do everything to ferry Antoine Griezmann away from Atletico this summer.
