Real Madrid fear an attempt arriving from Manchester City for midfielder Toni Kroos.
Marca says Real fear City could poach Kroos, despite Blues distancing themselves from the Germany international.
There is concern at the Bernabeu that City boss Pep Guardiola try to reunite with Kroos, who he managed at Bayern Munich, after Real made is clear they want to sign Paul Pogba.
Kroos left Bayern for Madrid in 2013 and has won two Champions league titles during his time in the Spanish capital.
