Paris Saint-Germain have made Thibaut Courtois aware of their interest in signing him and the Chelsea goalkeeper is open to their advances, a source close to the club told ESPN FC. However, while PSG are keen on Courtois, a number of things could influence whether the 25-year-old Belgium international actually ends up at Parc des Princes. According to the source, the Ligue 1 leaders' sporting director, Antero Henrique, has made signing a new goalkeeper a priority for next season -- along with a long-term heir to Thiago Motta's deep-lying midfield role -- because Alphonse Areola, Kevin Trapp and Lassana Diarra have not yet convinced him that they deserve to be guaranteed members of the starting XI. Informal talks between PSG and Courtois have taken place as the keeper has yet to commit to a new contract with Chelsea, but no formal interest has been registered. The source said that Courtois has indicated that he is not against the idea of potentially signing for PSG, but both sides made it clear during their meeting that there are certain factors that could influence a potential transfer. On PSG's side, UEFA's financial fair play watchdog is still a consideration, and until European football's governing body is totally satisfied with all aspects of the club's finances, the possibility of selling players remains significant.
