Benoit Badiashile, David Datro Fofana, and Gabriel Slonina have all been assigned shirt numbers by Graham Potter’s Blues.
Badiashile, who previously wore the number five shirt for AS Monaco, has chosen to wear the number four jersey for Chelsea, which was last worn by Andreas Christensen.
Fofana, on the other hand, will wear the number 27 jersey.
The Ivory Coast international previously wore jersey numbers nine and 20, but those numbers are now worn by Denis Zakaria and Pierre-Emerick Aubameyang at Stamford Bridge, respectively.
The club’s official website announced on Saturday that the 20-year-old, who joined Chelsea on Saturday, could face Manchester City in the FA Cup on Sunday. Badiashile is also a candidate.
Given Chelsea’s extensive injury list, both youngsters have a good chance of making their Chelsea debuts soon.
Slonina, who joined Chelsea last summer before going on loan to MLS club Chicago Fire, has been assigned the number 36 jersey.
Given the limited opportunities for games, it is unclear whether the young goalie will spend the rest of the season at Chelsea.
