Neymar's inclusion was the only change from the Barca side that won 2-0 at the Etihad in the first leg three weeks ago as the Spanish international midfield quartet of Sergio Busquets, Xavi, Cesc Fabregas and Andres Iniesta all started.
City were able to welcome back Messi's Argentine international teammate Sergio Aguero up front as Manuel Pellegrini made four changes in all from the first leg.
Joleon Lescott replaced the suspended Martin Demichelis following his red card in the first meeting between the teams.
Samir Nasri and James Milner also started with Jesus Navas, Gael Clichy and Alvaro Negredo dropping to the bench.
