Guardiola has achieved what nobody has in 148 years of history

The Catalan coach was criticised a lot for the phrase he said just before being knocked out of the Champions League: "I didn't come here to win it." As time goes by, the amount of titles won is proving him right because although he has not won the Champions League, he keeps on winning titles and making history on the City bench.
Man City played four domestic tournaments this season and Guardiola won all four. A feat which nobody had achieved. People had done it in their careers such as Bill Nicholson, Don Revie, Joe Merced, Kenny Dalgllish, George Graham, Sir Alex Ferguson and Jose Mourinho, but nobody had won all four in the same season.
Barcelona and Ajax, knocked out of the Champions League semi-finals against the odds, missed out on the treble; he can boast about this quadruple earned in nine months. Although he missed out on the Champions League once again, Guardiola's dominance in English domestic football increased.
And that was not the only thing he achieved. Against Watford, he equalled the biggest ever winning margin for an FA Cup final (6-0) which was achieved in 1903.
Finally, he has now won 27 titles in his managerial career and he will go level with Ottmar Hitzfeld with one more trophy.
