5) Not used to inheriting a struggling side
Perhaps most importantly, Guardiola is not used to taking control of a side that doesn’t already have the core ingredients to be successful. Although some rebuilding was needed at Barcelona, it could be argued that a lot of managers would have done well with a team containing the likes of Lionel Messi, Xavi and Andres Iniesta at their peak. At Bayern as well, Guardiola inherited a side that won the treble and could not repeat that success himself in his first season at the club. Much more work would be needed at Arsenal, who have not looked close to winning the Premier League or the Champions League in a long time.
