Keeper Adam Przybek and central defender Alex Henderson make their debuts and Barry Cotter returns to first-team action for the first time since April 2018 as manager Paul Lambert names his usual much-changed side for this evening’s second-round Leasing.com Trophy tie at Peterborough. No one who was in the XI at Coventry on Sunday is included in the 18.
Wales U21 international keeper Przybek (above), 19, joined the Blues in the summer after leaving West Brom following a trial last season.
Second-year scholar Henderson (below), 18, who is from Boxford near Sudbury and who joined Bury Town on loan at the weekend but is still able to play for the Blues, lines-up alongside stand-in skipper Cole Skuse at the centre of the defence.
Cotter - whose last first-team match was as a late sub in the 4-0 win at Reading in the penultimate match of 2017/18 - is at right-back and Myles Kenlock on the left.
The Blues again seem likely to play a three-man midfield with Emyr Huws joined by Brett McGavin and Idris El Mizouni.
Up front, James Norwood looks set to play down the middle with Jordan Roberts back after his toe injury on the left and Armando Dobra on the right.
There are more youngsters on the bench, academy keeper Jake Alley, left-back Tommy Smith, 16-year-old midfielder Liam Gibbs, who made his debut as a late sub in the last round, midfielder Tommy Hughes and strikers Tyreece Simpson and Ben Folami, who all also appeared earlier in the competition.
On-loan Spurs winger Anthony Georgiou is the only senior man among the subs.
Posh boss Darren Ferguson also rings the changes, making nine from the team which beat Dover Athletic 3-0 in the FA Cup on Sunday. Only Dan Butler and Joe Ward keep their places with strike pair Mo Eisa and Ivan Toney on the bench.
Peterborough: Chapman, Mason (c), Bennett, Butler, Ward, Barker, Woodyard, Kanu, Tasdemir, Jones, Dembele. Subs: O'Malley, Cartwright, Kent, Reed, Burrows, Eisa, Toney.
Town: Przybek, Cotter, Henderson, Skuse (c), Kenlock, McGavin, Huws, El Mizouni, Dobra, Roberts, Norwood. Subs: Alley, Smith, Hughes, Gibbs, Simpson, Georgiou, Folami. Referee: Graham Salisbury (Lancashire).
