Manchester City boss Pep Guardiola says this season's Premier League title victory has been the toughest of his career.

The Citizens were crowned champions on Sunday after beating Brighton 4-1 at the AMEX.

Guardiola's side finished with 98 points for the season, only one point ahead of Liverpool.

The former Barcelona and Bayern Munich boss told Sky Sports: "We have to say congratulations to Liverpool and thank you so much, they pushed us to increase our standards.

"It's incredible, 98 points, to go back-to-back. We made the standard higher last season and Liverpool helped us.

"To win this title we had to win 14 [league games] in a row. We couldn't lose one point.

"It's the toughest title we have won in all my career, by far."
