Real Madrid are preparing a raid on Liverpool for Raheem Sterling.

The Spanish giants have identified the teenage England winger as a future world star, but were planning to wait until next summer before making a move.

Sunday Mirror Sport understands, however, that the European champions are so concerned about the tendonitis knee problem that plagued Cristiano Ronaldo’s World Cup that they want to seal a deal for Sterling now.

The 19-year-old capped a sensational season with Liverpool by being one of England’s few outstanding players in Brazil.

He played in all three games for England as Roy Hodgson’s men bowed out at the group stages with just a single point.

But Sterling’s outstanding contribution against Italy has prompted Madrid to believe he is ready to handle a switch to the Bernabeu.

Madrid are ready to offer £25million-plus - despite still maintaining a strong interest in £70million-rated Liverpool bad boy Luis Suarez.
