Using numbers to prove Guardiola's greatness: Manchester City won 18 titles in their first 136 years, and 20 titles in the last 10 years.

Every summer is a season of farewells. This summer, for Manchester City fans, it is a searing emotion hard to say goodbye to, because Guardiola has ended his 10-year tenure with the club and will leave this summer. Many City fans are reluctant to part ways, and Guardiola emotionally bid farewell to the fans at the scene. Because work is work, Guardiola now wants to return to his family, spend time with his loved ones, move back to Spain, and win back his ex-wife's love.

Manchester City is a club with a long history. The Citizens were founded in 1980. Numbers may be cold, but they are also revealing, best illustrating Guardiola's greatness. The club has existed for 146 years. In the 136 years before Guardiola took over, City won only 18 trophies. Since Guardiola arrived in 2016, he has helped City win 20 trophies in ten years, including six Premier League titles and the club's first Champions League trophy, with four consecutive Premier League titles setting a new record.

Ten years pass in the blink of an eye. The summer of 2016 feels like yesterday, yet ten years have gone by. From his arrival to his departure, the companionship of these ten years has made City fans happy. If six Premier League titles and four in a row transformed City from a wealthy club into a Premier League giant, then the first Champions League trophy was the key to becoming a European elite. City won the Big Ears trophy, thus entering the ranks of Europe's top clubs. Every party comes to an end; it's hard to say goodbye, but the first priority for adults is family. Living in Manchester for ten years kept Guardiola away from his family, ultimately leading to divorce. Now, Guardiola, with the heavy bounty of 20 trophies in ten years, will return to sunny Catalonia to enjoy family happiness and win back his ex-wife's love. Though reluctant to see him go, as City fans, all we can do is wish Guardiola well!
