Real Madrid continue to scour the market for a left-back. Although it seems that Sevilla's Alberto Moreno is the most likely candidate to replace Fabio Coentrao, Sky Italia's Gianluca Di Marzio says the Spanish giants are planning to move for Southampton's young defender Luke Shaw.

The 18-year-old, who made his debut for Southampton in January 2012 against Millwall in a third round FA Cup tie, is already a key player in coach Mauricio Pochettino's line-up.

Shaw has broken into England national team this campaign, having made his debut as a replacement for Chelsea star Ashley Cole earlier this month.

A host of Premier League clubs have been linked with Shaw, including the two Manchester clubs as well as Chelsea, Tottenham and Liverpool.

Blues' boss Jose Mourinho, who is also interested in the Saints midfielder Adam Lallana, appears the favourite to lure the starlet away from the south coast this summer ahead of United, Spurs and Liverpool.

Real Madrid already have one product of Southampton's youth production line, Gareth Bale, who moved to the Santiago Bernabeu from Tottenham in a world-record £91m transfer last summer.
