Mario Kempes fears for Atletico Madrid once Diego Simeone leaves.

The Argentine legend says Atletico and Simeone are perfect for eachother.

"Atleti is the ideal club for Diego Simeone. The players obey him and defend him to death," he told La Nacion.

"What he says is taken as sacred. Everything's working out for him; he has earned it. He's always had good strikers who have moved on - Diego Costa, Falcao, Villa... but he has always somehow managed to find a replacement who fits into his system and works.

"He's getting the results but that's because he goes in search of results. When he leaves Atlético de Madrid, those lads are going to feel a little lost. The players who have moved away have never performed to the same level at their new clubs."
