Having collected 21 pieces of silverware in his relatively brief managerial career so far, Pep Guardiola is widely considered one of the best coaches in world football.
Indeed, when Manchester City announced his hiring earlier this year, it was thought to be the key move in helping the Citizens take the next step towards bringing consistent success to the Etihad.
But, despite his impressive reputation, it doesn't look like Guardiola has convinced everyone about his capabilities. That's after Franck Ribery, who played under the 45-year-old at Bayern Munich, tore into his former boss in a recent interview.

As reported by the English language version of Spanish publication AS, Ribery was far from complimentary about Guardiola.
"Guardiola is a young coach with a lack of experience," the Frenchman began. "Sometimes he talked too much…football is very simple."
Considering Guardiola brought three consecutive Bundesliga titles to Bayern as well as a DFB-Pokal cup triumph during his three years in charge, Ribery's comments are a little surprising. Back that up with his achievement at Barcelona, and they become almost ludicrous.
However, the veteran midfielder cited Bayern's UEFA Champions League semi-final defeat to Atletico Madrid last season as a particular example of the Spanish coach's apparent naivety.
“You can’t commit errors in the semi-final of the Champions League," Ribery lamented.
"Thomas Müller didn’t play from the start and Jerome Boetang, having recovered from the injury he suffered, also wasn’t picked and had to watch the game from the stands."
Manchester City have long sought to improve their fortunes in European football's biggest competition, and bringing in Guardiola to replace Manuel Pellegrini this summer was done in the hope of doing just that.
Hearing Ribery openly criticise the former Barcelona manager's decision-making at crunch times in that tournament will, then, be a concern for a lot of City fans who have high hopes for the campaign ahead.
Neverthless, the two Champions League winner's medals Guardiola has from his time at the Camp Nou will settle those nerves a little.
As for Ribery's other criticisms, it will certainly be interesting to see if any City players bring into question any of the new boss' methods.
Guardiola has already ruffled a few feathers with his strict nutrition rules - banning Samir Nasri from training from the first team until he sheds some weight - and he doesn't seem the type who will be afraid to make some bold calls to get the results he wants.
