His goal on Arsenal for the FA Cup is Kun's 166th goal for Manchester City, matching Tommy Johnson and being only 11 goals behind the top goalscorer in the club's history, Eric Brook. Sergio is still making history happen at City. When he scored on Arsenal after the agonizing 2-1 defeat for the FA Cup, he reached 166 goals with the Citizens. This places him alongside Tommy Johnson as 2nd top goalscorer in the club's history. Johnson is a historical figure of the club, playing for 10 years between 1920 and 1930, with 354 total games played between the League and the local tournament. Kun is just a stone's throw from Eric Brook, who holds the first spot. Brook, whose career spanned between 1928 and 1939, scored 177 times – which means Sergio is only 11 goals away of reaching that mark.
