Messi can have more impact than Ronaldo
Cristiano Ronaldo wasn't with the Manchester United squad that met up on Saturday night ahead of facing Manchester City in the derby, but the Blues won't be too concerned about whether he turns up at the Etihad or not.
Instead, Guardiola will be looking to which of his players can be matchwinners for City, and the key to that might be Ronaldo's world-class rival Lionel Messi.
