Real Madrid star Cristiano Ronaldo is keeping a close eye on Manchester United whizkid Marcus Rashford.

Rashford has impressed for Jose Mourinho’s United this season, along with England.

Ronaldo has noticed and Don Balon says he has approved a move for Rashford if Real president Florentino Perez is unable to secure the signing of top target Harry Kane.

The La Liga champions know it will be difficult to get a deal over the line for the Tottenham striker.

The signing of Rashford could mean Karim Benzema would stay at the Bernabeu with the 19-year-old being slowly introduced into the fold by Zinedine Zidane.
