The former Brighton goalkeeper is spending his first season at Stamford Bridge.
Robert Sanchez has struggled to find his best form at Chelsea since completing a £25m summer switch.
The Spanish goalkeeper made a total of 23 Premier League appearances for Brighton last season, keeping six clean sheets. However, the Seagulls allowed his departure after receiving an offer from Chelsea in the summer transfer window.
The Blues, who had already sold Edouard Mendy to Al-Ahli, went on to make Sanchez their No.1 keeper, sending Kepa Arrizabalaga to Real Madrid on a loan deal.
Chelsea have started the season by collecting only four points from their first four matches of the new campaign, conceding five goals. The Blues’ defensive issues are evident, but it seems that Sanchez is also out of form.
According to Whoscored, the Chelsea goalkeeper has the worst save success rate (54.5%) in the Premier League so far this season. FBREF data shows that Sanchez has made a total of six saves this season, conceding 1.25 goals per 90 minutes.
Djordje Petrovic and Marcus Bettinelli are the two backup goalkeepers at Mauricio Pochettino’s disposal. However, the latter is unavailable due to an injury he sustained during the pre-season.
After the international break, Chelsea will return to action with a match against Bournemouth on September 17.
