With Pep Guardiola's future at Manchester City uncertain, the club has reportedly identified his potential replacement.
Rumours in England suggest that the Spaniard will be offered a new contract, with his current deal expiring at the end of the 2020/21 season.
City, however, are also trying to plan ahead just in case Guardiola decides against committing himself further to the Citizens by lining up potential replacements.
According to the Daily Mail, RB Leipzig manager Julian Nagelsmann is on the club's radar should the former FC Barcelona and Bayern Munich boss not wish to extend his stay at the Etihad beyond this campaign.
Guardiola could reportedly look to move on from the Premier League side in 2021 after making his worst-ever start to a season in his managerial career.
City have claimed just eight points from their first five EPL matches of the campaign, and do not yet have a positive goal difference, something their fans are usually accustomed to early on in a new season.
Guardiola arrived at City in 2016, and has since added eight pieces of silverware to his and the club's trophy cabinet.
