Guardiola and Diego Simeone are the best of the Middle Generation of coaches, they are of the same age, they are also midfielders, and they have also led their team to play in world football!
The difference is that Guardiola came to Manchester City in 2016 and took less than 6 years to oust the city's sworn enemy Manchester United from the throne and turn the sky in Manchester blue; Simeone took over Atletico Madrid in 2011, it took 10 years, but he could not shake the city's sworn enemy Real Madrid, And Madrid still remained pure white!

Guardiola can be described as the peak of his debut, and has had three coaching experiences in Barcelona, Bayern Munich and Manchester City so far. In the world's famous coach rankings, there will always be an iron-clad Guardiola flowing soldier, in the summer of 2016, Guardiola decided to join the Etihad, just to prove with strength, passing football can also run rampant in the Premier League!
In 6 years, Guardiola has paid off every penny spent by the Manchester City boss, and Manchester City has achieved the sublimation of the giant temperament in these 6 years! 3 Premier League titles, 1 Champions League final, 4 League Cup titles and 1 FA Cup, Guardiola has won 10 Premier League Coach of the Month, turning the Premier League into a stage for Manchester City to thrive!
The sky over Manchester has turned blue exclusive to Manchester City, and Guardiola has completely crushed Manchester City's boss Manchester United, subverted the Premier League pattern and is likely to win his fourth Premier League title this season! Looking at the whole of Europe, in terms of squad strength, the only teams that can compete with Manchester City may be Liverpool, Real Madrid and Bayern, although they have only reached the Champions League final once so far, but no one dares to underestimate this Manchester City, the biggest favorite of this season's Champions League champions is still them, Guardiola's tactical concept has been deeply implanted in manchester City's DNA!
At the end of 2011, Simeone was appointed as the head coach of his old club Atletico Madrid, starting his brilliant coaching career. When Guardiola took over Manchester City, the team was already a Premier League champion team, and when Simeone took over Atletico, the team was only the 10th middle team in La Liga, and 10 years later, Atletico Madrid was already a la Liga giant team that won 8 titles and reached two Champions League finals.
Simone built the Legion of Sheets into a legion of steel, steely defense and a belief that every inch of land must be fought, winning the title of "Atletico"! Falcao, Diego Costa, Suarez and other players, coupled with Simeone's tactical system bonus, Atletico madrid in the double clamp between Real Madrid and Barca to kill a bloody road, ten years of eight crowns, including 2 Europa League, 2 European Super Cup, 2 La Liga champions, 1 Copa del Rey and 1 Spanish Super Cup, Simeone's coaching philosophy has brought qualitative changes to Atletico Madrid!
It is such a great Simeone, but still can not shake the supremacy of the city's mortal enemy Real Madrid, during the same period Real Madrid changed 7 managers, the record is 4 Champions League champions, 4 Club World Cup champions, 3 European Super Cups, 3 La Liga champions, 4 Western Super Cups and 1 King's Cup, both the number and quality of champions are far more than Simeone, including two Champions League finals against Atletico Madrid to win the championship!
Simeone has worked hard enough, but Madrid has not turned red and blue because of the rise of Atletico, and the pure white of Real Madrid is still the main color of the city, unassailable!
It seems that Guardiola's talent and strength are higher than Simeone's, if the two sides exchange teams to coach, what will become of the current world football landscape?
