Atletico Madrid are eyeing two of Real Madrid's players for next season.
With Real preparing a hostile raid on Atletico for Theo Hernandez, Diario Gol says a move the other way is also being discussed.
Atletico coach Diego Simeone is keen on Real striker Mariano Diaz and winger Lucas Vazquez.
Atletico have already contacted Lucas about a summer move, but the Castilla graduate is reluctant. While flattered by the interest, he has no interest in moving to Real's bitter rivals.
The opposite is true in Mariano's case, who has initiated discussions with Atletico about a summer switch.
