Manchester City's Carabao Cup win at Oxford in 2018 will be remembered for Phil Foden's first goal of many for the club, but it also featured another significant selection from Pep Guardiola.
In a game against League One opposition, Guardiola rotated and experimented, with Foden, Aro Muric and Brahim Diaz starting at the Kassam Stadium.
When the City team sheet was revealed, fans may have thought Guardiola would offset that inexperience with a back five as Vincent Kompany, Nicolas Otamendi and John Stones were all named in the starting line-up.
