There has been increased scrutiny of Chelsea head coach Liam Rosenior, with his decision not to name a first-choice goalkeeper chief among the criticism he now faces.
Before the Englishman's appointment in January, Robert Sanchez had been former boss Enzo Maresca's undisputed first choice for almost his entire 18u2011month tenure.
However, Sanchez has been in rotation with understudy Filip Jorgensen since his poor display in a 2-1 defeat at Arsenal.
The promoted Dane, 23, produced a steady performance in a win at Aston Villa, but a sloppy pass in his second outing led to Paris St-Germain's third goal as Chelsea's Champions League hopes collapsed in a 5-2 defeat at Parc des Princes.
