Barcelona coach Ronald Koeman says he's yet to decide where Frenkie de Jong will play against Real Madrid.

Koeman hasn't ruled out fielding De Jong at the back.

He said, "The best thing is that he can contribute a lot in both positions, both as a centre-back, passing the ball out, and in the midfield reaching the opposition area. Tomorrow I'll talk to the players and we'll decide."

On Lionel Messi, Koeman continued: "Hopefully it will be decisive for us. We need the best Messi, but also the best Barça. We need Leo."

The Barca coach was also asked about Sergio Ramos' contract situation at Real Madrid.

He added: "The best thing for our League is that the best players can stay until the end of being able to play. Hopefully Ramos will continue at Real Madrid and Ramos will continue with us."
