The majority of players who cross paths with Pep Guardiola cannot praise him highly enough for his passion, attention to detail and of course, his brilliant managerial record.
However, every so often a brave maverick speaks out against the Spaniard - the most famous example being Zlatan Ibrahimovic - to suggest Guardiola might not be quite the crowd pleaser his persona usually implies.
Less than a month into Carlo Ancelotti's reign at Bayern Munich, Franck Ribery has already gone out of his way to heap praise on the new manager and take a subtle dig at the Italian's predecessor.
Guardiola's tenure at the Allianz Arena was a frustrating one for Ribery. Struggling with various disruptive injuries for the last three years, the Frenchman has been unable to rediscover the form that saw him finish third in the 2013 Ballon d'Or.
Making just 50 appearances for Bayern under Guardiola, Ribery dropped behind Kingsley Coman and Douglas Costa in the pecking order last term and the winger has admitted he did not feel trusted in the previous regime.
In an interview with Kicker, Ribery said: "I feel free and I am fully motivated. Carlo Ancelotti is a gift for the club. Since Ancelotti has arrived, I feel more trust.
"He's a great coach. I need people like him, Jupp Heynckes or Ottmar Hitzfeld. I need this trust in me, to play off my strengths."
Ancelotti clearly has plenty of faith in the 33-year-old, based on the evidence he has started all three of their pre-season matches so far this month, scoring twice along the way.
Ribery is feeling confident he will back to his best in the upcoming campaign and added he will be more motivated to perform with Ancelotti at the helm.
"It all depends on things like trust, respect and proximity. Then I cannot only give 100 percent - I can give 150 percent." the French international said.
"With Ancelotti, we can reach something great and I'm really looking forward to the next season."
Ribery moved to the German capital in 2007 and despite now being considered one of the more experienced members of the squad, has no desire of taking a backseat role while Ancelotti is in charge.
