Achraf Hakimi admits he's spoken with Borussia Dortmund teammate Paco Alcacer about the pair of them playing at the Santiago Bernabeu.
While Hakimi is on-loan at BVB from Real, Alcacer has just been sold by Barcelona to the Germans.
"Here I have the continuity I needed, I feel more mature, more important, more a player," said Hakimi.
"I have to go back to Madrid in 2020 but in two years' time anything can happen."
Asked if he and Alcacer had spoken about playing together for Real, he added: "We've talked about it once."
