Grayson, who recently recruited Tony Parkes and AndyWelsh to his backroom team, has been told there is no timescale for him to worry about when it comes to a permanent managerial appointment.
Former Manchester United assistant coach Brian Kidd has been recruited as technical development manager and will oversee the club's youth system whilst AndyWelsh, formerly an integral part of Leeds United's youth development, will run City's own domestic academy.
Wayne Hennessey, David Edwards and Sam Vokes are off to Denmark with the Welsh squad, while Andy Keogh and Kevin Foley link up with the Republic of Ireland to face Poland in Dublin.
