The Belgium international feels the club's youngsters are privileged to work under a top coach like the Spaniard and praised the former Barca boss' methods
The 42-year-old took charge of the Champions League holders ahead of the 2013-14 campaign following a year-long sabbatical after leaving the Catalan club, and Van Buyten feels Guardiola is the ideal coach for young players in the same way as his predecessor, Jupp Heynckes.
"Every coach has his own philosophy, his own way of doing things," Van Buyten told the official Bayern website. "Our young players can count themselves lucky to be working with top coaches like Guardiola and Heynckes.
"They can improve their game quicker than before. The coach encourages us to demand the ball more and not to worry even when you're under pressure.
The 35-year-old is one of the club's longest-serving players, and claims that the training drills under the new regime encourage players' calmness and technique.
"In the training sessions we play three against one and three against two in a small area of three or four metres - we get 20 metres in a match! That's much easier," he continued.
"The coach always says: 'Never forget: If you can do it in three or four metres then why not in 20? Therefore: Don't worry! Be courageous!'"
