There have been a lot of rumors and even some training pictures floating around, but the squad numbers for these three players have no officially been confirmed by the club. KDB will wear #14, Hazard will wear #17, and Marin will wear #21. This is relatively big news for those of you (like myself) who are avid jersey collectors, as you can feel confident in purchasing these players' shirts now*. *there is still a very slight chance that Chelsea sign Luka Modric, and some slight possibly within that already hypothetical situation that they'll give him the #14 and ask KDB to switch (or send him out on loan).
