Chelsea midfielder Mason Mount endured a dismal performance in defeat to Southampton on Saturday.
The Blues' poor run carried on as they lost 1-0 to bottom-of-the-league Saints, which means they have won just once in 10 matches so far this year.
Mount was among the most disappointing performers against Ruben Selles' men.
The versatile forward won none of his six ground duel battles and failed on both of his take-ons.
The England international was also unsuccessful on his one and only tackle attempt and couldn't complete a cross.
The 24-year-old completed eight out of 13 passes, most of which were to the back, until he was taken off for Kai Havertz on 64 minutes.
Chelsea goalkeeper Kepa Arrizabalaga proved to be a better passer as he completed all of his 14 attempts.
