Real Madrid had scouts posted to France last night.
While Real were playing out a 0-0 draw at Barcelona, top level scouts were attending Rennes' Coupe de la Ligue victory over Amiens.
L'Equipe says two representatives from Real were in the stands to check on Rennes midfielder Eduardo Camavinga.
The 17 year-old has emerged as a priority target for Real president Florentino Perez with talks already underway with his minders.
Camavinga's current deal runs to 2022.
