But boss Robins is set to field the closest 11 possible to the one that will start the season opener against Accrington next week, and expects a tough test.
"Whoever Manchester City send, it will be a good side, no doubt about that." he told the Star.
City also face Barnsley at Oakwell, and are set to split their squad travelling to South Yorkshire with a mixture of fringe first teamers and established stars.
Kick off is 3pm and priced £10 adults and £5 all concessions.
