Cristiano Ronaldo would have scored nearly double the goals he has this season had he joined Manchester City, rather than returning to Manchester United.
Peter Barnes, one of only 34 players to have played for City and United, believes Ronaldo would have thrived under Pep Guardiola in the blue half of Manchester.
Ronaldo has scored 15 goals in his second spell at United, who hijacked his proposed move to City last summer with a crucial intervention from his former boss Sir Alex Ferguson.
