With 18 major titles to his name a mere five-and-a-half years into his managerial career, Pep Guardiola is undoubtedly one of the greatest managers of the current generation.
Indeed, the Spaniard has already won more trophies than Carlo Ancelotti (17) and is closing in on fierce rival José Mourinho's total of 20. On paper, there is nobody in the modern game who can compete with Guardiola's success rate.
However - until he has achieved domestic and continental success with a club that has not been nearly as successful in recent years as Barcelona and Bayern Munich - he cannot be compared with either the reigning European champion or the Chelsea boss.
Ancelotti better than Pep?
In November 2001, Ancelotti took charge of an AC Milan side that was struggling under Fatih Terim and had had finished 6th in the league the previous season. Within two and a half years, he guided the Rossoneri to both European and Serie A glory.
Milan went on to repeat their Champions League success under Ancelotti in 2007, despite having been rocked by the Calciopoli match-fixing scandal a year earlier. They have not won the competition since he left the club.
Mourinho also better than Pep?
Indeed, the only Serie A manager to win European club football's most coveted trophy since Ancelotti was José Mourinho in 2010. However, even this success pales in comparison to his achievement of masterminding the biggest shock in recent Champions League history - winning the title with FC Porto in 2004.
When Mourinho was appointed manager in January 2002, Porto had not so much as won the Portuguese league in the previous three years. No Portuguese team had been European champions since 1987 and the Champions League has not had another winner since Mourinho moved to Chelsea. He was also successful at domestic level, winning back-to-back league titles.
Mourinho and Ancelotti have both enjoyed success whilst in charge of Real Madrid and Chelsea, with the latter also winning trophies with Paris Saint Germain and Juventus, but it is their astronomical success whilst in charge of less-fancied teams that set them apart from Guardiola.
Pep must also do it the hard way
The Bayern boss inherited a team of ready-made German and European champions from Jupp Heynckes. The Barcelona team he took charge of in 2008 had won both the Champions League and La Liga titles just two years earlier.
His success with both clubs has been impressive, but he will never be in the same league as Mourinho and Ancelotti until he proves that he, too, can do it the hard way.
