Mowbray reshuffles his back line as Romain Vincelot drops in to centre-half and Jacob Murphy will operate at City's no.10...
Tony Mowbray makes two changes to his starting line-up as City trio are unavailable due to their respective international call-ups.
Forward pairing, James Maddison and Adam Armstrong as well as defender Jack Stephens are all away on duties with the England youth setup.
Romain Vincelot fills the void left by Stephens at centre-back as Gael Bigirimana partners John Fleck in holding midfield.
Jacob Murphy slots in to the no.10 role, with Andy Rose and Joe Cole retaining their positions in midfield.
Marc-Antoine Fortuné is given the nod up top, as new signing Jodi Jones is available from bench after impressing in the U21s squad midweek.
