Ross Barkley (Chelsea)
The Chelsea midfielder had his number 8 shirt handed to Mateo Kovacic at the start of the season and he was only registered with a new number (18) near the end of the transfer window when it became clear he wasn’t leaving.
Barkley has never played under Thomas Tuchel, having been sent on a season-long loan to Aston Villa by previous head coach Frank Lampard at the start of last campaign.
