Barcelona coach Ronald Koeman insists no-one knows how the handball is being interpreted.

Koeman spoke to the press ahead of Barcelona's LaLiga Santander fixture with Levante.

Yet one of the main topics of discussion was the controversy in Real Madrid's 2-2 draw with Sevilla, where Eder Militao was penalised for a handball in the area.

"If Real Madrid are complaining, it is their problem," Koeman said at the press conference.

"Even the referees have doubts, [and] us coaches and players do not know when it is handball.

"But it is not only in Spain, it also happens in other leagues."
