Diario Gol claim that Ramos has instructed Real to steer clear of Chelsea star Eden Hazard and also PSG star Kylian Mbappe.
Eden Hazard has been heavily linked with a move to the Bernabeu in recent months.
Real boss Zinedine Zidane and club president Florentino Perez are both said to be big admirers of the attacker.
Diario Gol report Ramos told Real they shouldn’t sign Hazard this summer.
They claim the Spain international warned Perez that Eden Hazard would disrupt the Real dressing room, as well as having doubts over his injury.
Hazard has been clear on his Chelsea future and the winger also revealed he could be open to joining Real in the future.
Hazard told Spanish newspaper Marca: “At the moment I’m good in England.
“I play in one of the best teams, but yes, the Spanish League is special.
“Why not one day? Of course, for the moment I’m here.
“I think now, at this moment, Real Madrid is the best team in the world.
“They have won everything and have good players, a great coach.
“Now, the Champions League is very difficult to win. It happens as in the Premier League, anyone can win. You never know.”
