The Spaniard's sibling Pere has revealed the lengths to which the next Bayern Munich boss has been preparing for his new post
The former Barcelona coach is set to take charge of the European champions at the end of the month after agreeing a deal to replace current boss Jupp Heynckes during the winter.
His brother, who also acts as his representative, has revealed that the 42-year-old began taking German lessons as early as November while on sabbatical leave in New York, claiming his efforts to master the language have matched his usual meticulous approach to detail.
"Pep has been as always - obsessive," Pere told Der Spiegel. "Four hours every day, like a madman. Only a stubborn dog does this.
"It is absurd. As you meet your brother for lunch, the guy is talking German continuously with his teacher!"
Guardiola is expected to lead his first training session with the treble-winners on June 26.
