Chelsea star Cesar Azpilicueta is being tracked by Manchester United, Paris Saint-Germain and Athletic Club Bilbao ahead of coming summer transfer window, according to AS. Antonio Conte, according to the publication, would be open to parting ways with the player should any suitors pay a fee of around €15m (£11.8m, $16.9m).

The 26-year-old defender moved to the Blues from Marseille in the summer of 2012 in a deal worth around £6.5m. Even though the former Osasuna academy product was originally a right-back, he has established himself as the first-choice left-back after beating out Ashley Cole for the position.

Azpilicueta became a favourite for Jose Mourinho in following seasons and remained unmovable in the Portuguese manager's line-ups, despite Chelsea spending big in bolstering the position in the forms of both Filipe Luis and Abdul Baba Rahman.

But AS now suggests his future at Stamford Bridge could be uncertain amid Mourinho's interest in a reunion at Old Trafford.

The Spanish publication adds that United may face competition from both Athletic and PSG, indicating that incoming Chelsea boss Conte would be open to negotiate at around £11.8m, Azpilicueta's defensive profile would be anathema to the Italian boss's plans should he decide to implement the 3-5-2 with two wing-backs that he used both at Juvents and with the Italian national team.

AS claims Mourinho will try to take advantage of the situation to lure him to United, butt adds Athletic and PSG could have an advantage over the Red Devils asthe Blues would rather not to bolster a Premier League rival's.

PSG's expected new manager Unai Emery is also said to be keen on signing his compatriot as Azpilicueta already knows Ligue 1.

Meanwhile, Athletic are also ready to battle for his services. They will play in the Europa League next season and AS points out that the Chelsea star has two good friends at San Mames in Mikel San Jose and Raul Garcia.
