Real Madrid are reportedly keen on prising highly-rated 17-year-old Seung Woo Lee away from Barcelona.
The youngster, who is regarded as one of the best talents in La Masia, is one of the main reasons why Barca are currently banned from signing new players, with his arrival closely scrutinised by FIFA.
As a result, Lee has been unable to play for the past year and will not be able to represent Barca until 2016, which is believed to be a concern for the teenager.
According to Marca, Real Madrid are closely monitoring developments and could move for the South Korean over the next couple of weeks.
Barca, however, are expected to strongly repel the interest from the Bernabeu.
