EXCLUSIVE | By Chelsea correspondent Tony Hughes

Paris Saint-Germain have made an enquiry for Chelsea playmaker Oscar, Football Insider sources understand.

The French champions have contacted the London club to ascertain their interest in selling the Brazil international this summer.

Football Insider understands that manager Jose Mourinho is willing to sanction the sale of Oscar but wants the Premier League leaders to find a blue-chip replacement.

Oscar, 23, has fallen down the pecking order at Stamford Bridge in recent months after being a first-team regular in the opening half of the season.

Football Insider sources have learned that Mourinho is not convinced that Oscar’s style of play is ideally suited to the Premier League, particularly in away matches.

The Portugese is ready for Chelsea to cash in on the Brazilian, who was signed from Internacional for £25m in the summer of 2012, and source a replacement.

Oscar has started 26 of the west Londoners’ 34 league matches this season, and four of their eight Champions League games, but he has frequently been dropped been sidelined in recent months. He was dropped from the side for the Capital One Cup final win over Tottenham and was on the substitutes’ bench for the 3-1 win at Leicester City on Wednesday night.

Juventus are among the clubs who have been linked with Oscar, although it is unlikely the Serie A leaders would be willing to meet Chelsea’s £40m valuation.

That price tag is unlikely to deter PSG, who are poised to spend big in this summer’s market despite the restrictions of Financial Fair Play.

Chelsea have sold some of their big-name players for substantial profits since Mourinho returned to Stamford Bridge two years ago, with David Luiz, Juan Mata and Kevin de Bruyne among those who have been off-loaded.
