Not many managers can claim to have coached some of the biggest clubs in Spain, Italy, England, France and Germany.
And only one person can claim to have won the Champions League on three separate occasions and reached the final four times.
Carlo Ancelotti has enjoyed success everywhere he has been and along with Pep Guardiola and Jose Mourinho, is considered to be one of the best managers in the world.
Adapting to different countries, playing styles, competitions and players is no easy task but the Italian has always taken it in his stride and always finds the recipe for trophies.
But he is also one of the more grounded personalities in the dugout today. Unlike someone like Mourinho, Ancelotti is adverse to the use of mind games and dedicates his entire focus on his team, players and the next match.
The 57-year-old is still young enough to add plenty more trophies to his extensive list of honours but having already managed AC Milan, Chelsea, Paris Saint-Germain, Real Madrid and Bayern Munich, there is the danger he could be running out of top teams to coach.
And in an interview with Marca, Ancelotti has already ruled out four potential opportunities in the future as a mark of respect to his previous allegiances.
When asked if would ever return to Spain to manage either Atletico Madrid or Barcelona, Ancelotti said: "No, I will never train them.
"I respect the history of the rivalry and in the same way, I couldn't train either Lazio or Inter.
"I have a lot of respect for Atletico and Barcelona, but I can't train them because I've coached Real Madrid for two years."
Ancelotti will be back in Spain later this year after his Bayern team were put in the same group as Atletico in the Champions League.
The Vicente Calderon is one of the few football stadiums the Italian is yet to secure a win at and he has admitted that will act as his main motivation when the two teams clash on September 28.
"I expect and want to win because I have never managed a victory there with Chelsea or Real," Ancelotti continued.
"Bayern already know how good Atletico are because they eliminated us last season.
"We've not forgotten."
