Chelsea among clubs interested in PSG's Javier Pastore - source

Paris Saint-Germain playmaker Javier Pastore is the subject of interest from Chelsea, an Italian club and a Chinese outfit, a source close to the Argentina international has confirmed to ESPN FC.

Pastore is "only thinking about PSG" at present, the source stressed, but admitted the 27-year-old's future at Parc des Princes is far from certain with the French champions set to consider the his future over the next few weeks.

Chelsea coach Antonio Conte is known to be a fan of Pastore since his time with Palermo in Serie A and the Italian tactician has already registered an interest in signing the player, should he ultimately leave Paris.

The interested Italian and Chinese clubs are unnamed but the offer from the Asian outfit is thought to be of significant financial value.

Pastore has recently returned to training with his teammates after a lengthy absence because of a recurring calf injury but the source revealed the South American is expected to be fit enough "to travel" to Basel as part of PSG's squad for next week's UEFA Champions League Group A clash.

Les Parisiens' No. 10 has been plagued by injuries over the past few seasons and the Ligue 1 giants are believed to be running out of patience with the former Palermo man, with Unai Emery surprised by the player's fragility.

The Spaniard had initially planned to make Pastore a key player in his starting XI but the mercurial Argentinian's fitness issues have meant he has only been able to feature in four league matches so far this campaign.

The frequent unavailability of the attacking midfielder is believed to be one of a number of contributing factors towards Emery's switch from a 4-2-3-1 formation earlier this term to the possession-based 4-3-3 style PSG played with under predecessor Laurent Blanc.

Pastore extended his contract until 2019 back in the summer of 2015, but with Giovani Lo Celso set to arrive from Rosario Central at the start of next year, the Ligue 1 champions could be tempted to cash in.

However, should Pastore prove his fitness and rediscover some form before Christmas, he could be given until the end of the season to prove he can look after himself and keep his recurring calf injury at bay -- ultimately saving his PSG career.
