The Spain worldwide told City's official website following a 2-1 victory over reigning champions Leicester: "The final weeks of the season have been tough, but we could win against Leicester and I'm very happy for these three important points".
The manager indicated last week he had already decided whether to keep Yaya Toure, Gael Clichy, Bacary Sagna, Willy Caballero, Jesus Navas and Tosin Adarabioyo.
A statement released by City said: "Pablo has informed the club he will move to pastures new, but leave behind many happy memories". I never saw one player in my life go to the pitch and not try to win the game.
The Spaniard can look forward to a busy transfer window after the season ends, as he looks to build a squad capable of fighting for the league title and mounting a challenge in the Champions League.
Asked about the Arsenal boss' comments, Guardiola said: "I don't understand how the managers speak for the other clubs and the other teams".
Though there are a number of first-team player contracts now under consideration, Pablo's situation is the only one that has been fully finalised.
No US plane allowed to fly
The Astana talks were meant to shore up an oft-violated ceasefire which was originally agreed in December. But US participation has been lacking and Syrian rebel groups are not stakeholders.
Fabian Delph is also out for the rest of the season but Guardiola could welcome back Sergio Aguero and John Stones.
Manchester City took a step closer towards guaranteeing a top-four finish in the English Premier League with a 2-1 win over Leicester City at Etihad Stadium, but were helped by a disallowed Riyad Mahrez penalty. "When you play against them you understand why they were champions", Guardiola added.
Earlier this term it looked as if all five players would be certain to face the exit door come the end of this campaign.
"If we didn't play for anything it would be different".
"There have been times throughout the season where we deserved a bit more, but today we got that luck and the three points". "I realised if I touched it I would be offside so I left it", Sterling said.
