Southampton left-back Luke Shaw is widely-regarded as one of the hottest properties in the Premier League at the moment, with Manchester United, Chelsea, Liverpool, Tottenham Hotspur, Manchester City and Real Madrid all linked with big-money bids for the talented youngster this summer.
The 18-year-old has been in such impressive form in England's top-flight this season that he's even being tipped for a spot in Roy Hodgson's Three Lions squad for the 2014 World Cup in Brazil, potentially at the expense of veteran full-back Ashley Cole.
With over 50 first-team appearances for the south coast club already in his fledgling career, Shaw is expected to have a bright future in the game, whether that's at St Mary's or elsewhere.
Given the level of interest in his signature, the talented teenager's valuation has skyrocketed over the past 12 months, with a £30million figure being mooted in some reports.
If Shaw was to leave Saints for that fee, it would make him the most expensive ever full-back in football history, and also place him among the top 10 most expensive defenders on the planet - not bad for a player that doesn't celebrate his 19th birthday until July.
Mauricio Pochettino will be desperate to keep Shaw for the 2014/15 campaign, but with a bidding war between some of Europe's most high-profile clubs likely to ensue as soon as the transfer window reopens, Southampton could be forgiven for selling the exciting young starlet this summer.
