Kyle Walker missed Manchester City training on Monday after limping out of their match with Aston Villa.
Kalvin Phillips was back with the group after his recent absence and new signing Manuel Akanji was also present, but there was no sign of the experienced right-back before the group flew out for their Champions League game with Sevilla. Walker's absence does not rule him out of Tuesday's match but it would be highly unusual for a player to miss a training session a day before the game yet still be involved in it.
Joao Cancelo, Sergio Gomez, Rico Lewis and Josh Wilson-Esbrand were all involved and two of those four could start in Spain, although John Stones and Nathan Ake can also play full-back. Pep Guardiola will likely give an update on Walker and the rest of his squad when he holds a press conference on Monday evening (6.30pm BST start) ahead of the game.
