Aaron Wan-Bassaka's extraordinary introduction into English football is in line to continue against Chelsea with the 20-year-old facing the task of marking Eden Hazard on Saturday.
Crystal Palace manager Roy Hodgson has Timothy Fosu-Mensah available at right-back again, but is considering sticking with Wan-Bissaka after his fearless performances against Tottenham and Manchester United.
The academy youngster wanted to leave Palace in January for first-team football but stayed and has broken through because of injuries to Hodgson's back line.
After successive starts against Spurs and United, a third could follow at Chelsea, and Hodgson hopes we are witnessing the start of a promising Premier League career.
