Manchester City chairman Khaldoon Al Mubarak has vowed that Pep Guardiola should have a new-look squad in time for the Club World Cup.
City fly to the United States on June 12 ahead of the tournament, with a temporary transfer window opening this Sunday and shutting two days before they jet off.
Al Mubarak admitted that City were not aggressive enough in reshaping the team on the back of sealing a fourth consecutive Premier League title last summer and insisted the same mistakes will not be repeated.
