Real Madrid will reportedly target Liverpool defender Glen Johnson and Tottenham Hotspur's Kyle Walker at the end of the season.
It is understood that Madrid boss Jose Mourinho is keen to add a right-back to his squad, and according to Marca, could raid the Premier League.
Johnson, 27, is seen by many in Spain as an ideal candidate, but 21-year-old Walker has also impressed for Spurs and England this season.
Madrid are currently six points clear at the top of La Liga.
