Real Madrid president Calderon: We'll be careful with new signings

Real Madrid president Ramon Calderon says they will be careful with their summer market work.

He explained: "We must not spoil this squad.

"This team needs a few drops to add quality, but without breaking what we have."

"We have achieved such unity that we must not break it. The players we bring in must lift the quality of the squad, but also possess the right character, behaviour, attitude, family life .... all this is key."
