Southampton fullback Luke Shaw is being urged to snub interest from Chelsea.

The Blues want the £10million-rated Southampton left-back, 17, after his impressive debut season, says The Sun.

But Graeme Le Saux, a former Chelsea and Saints left-back, says Shaw needs to tread carefully.

Ashley Cole is first choice at Stamford Bridge, with fellow England star Ryan Bertrand his understudy.

Le Saux said: "Luke is a good young prospect, but I think it is important that he develops and plays first-team football."
