Manchester City chiefs Ferran Soriano and Txiki Begiristain have the names of between three and six managers that could replace Pep Guardiola as manager.
Guardiola's reign as City manager will be a tough act to follow, having won six major trophies in three-and-a-half seasons.
The Spaniard's future at Etihad is constantly coming under speculation, with numerous links to Juventus and Paris Saint-Germain over recent years.
But, Guardiola is still contracted to the north-west club until at least the end of the 2020-2021 campaign.
City chiefs have already started to think about Guardiola's replacement, according to The Athletic.
Given Guardiola's unique philosophy, Soriano and Begiristain believe that there's only between three and six managers in world football that could succeed the Spaniard.
Patrick Vieira falls into that category, having adopted Guardiola-style tactics as a manager.
The Frenchman became the Citizens' Under-23 boss after hanging up his boots in 2013.
The former Arsenal midfielder spent two-and-a-half years learning his coaching trade, before heading to New York City FC in 2015.
Vieira guided NYCFC to new heights in the MLS. He took them from a 17th finish club to a team that finished fourth the following campaign.
He's also working wonders at Nice in Ligue 1, and they're currently pushing for a Champions League qualification spot.
After City were handed a two-year ban from European competitions by UEFA, speculation increased surrounding Guardiola's future.
