Victory over the Seagulls saw Manchester City break Chelsea's record of 95 points in a single season set in 2004-05.
Thierry Henry, for Arsenal in 2002-03, is the only player to reach 20 assists in a Premier League season. That is held by Manchester United who won the league in 1999/2000 by 18 points, and are now 20 behind City.
"What I like the most with Leroy, seeing his outstanding performance, finishing the game and I felt he could do better", he said. I think, especially, the Brighton team didn't want me to score but the most important thing was we broke the record, we scored more goals.
Guardiola praised the 22-year-old for his display, days after City celebrated their Premier League title. "Tomorrow, we are going to play for Yaya".
He also received a huge cheer when he picked out his winning goal against arch-rivals Manchester United in the 2011 FA Cup semi-final as his favourite moment at the club.
The midfield behemoth was signed in 2010 from Barcelona and became one of the most crucial figures as City turned from also-rans into a dominant force.
Guardiola also said it was also fitting farewell to Yaya Toure on his final appearance for the club after eight years at the Etihad Stadium. "Once, a team will arrive and do better than us, but they will have to do really good". I said I am going to show you the way.
However, Guardiola always valued Toure's influence as a player, on and off the field.
Captain Vincent Kompnay gave his armband to Toure for the night and was to quick to praise his long-time teammate, who he lifted the Premier Leeague trophy with on Sunday.
"He has helped make the club bigger and bigger and bigger", City manager Pep Guardiola said on Tuesday, a day before Toure plays his last home match for the club against Brighton. "Thank you for being a wonderful teammate both in the dressing room and on the pitch".
