Manchester City striker Sergio Aguero has signed a new five-year deal, the Barclays Premier League club have announced.
Manchester City have "too many players" and could allow John Guidetti and Scott Sinclair to leave before the end of the transfer window, according to Manuel Pellegrini.
The City boss admitted he must trim his squad before adding any further recruits, as City fight to comply with Financial Fair Play constraints.
Porto capture Eliaquim Mangala could be City's final summer signing unless the club can offload Sinclair and Guidetti, Pellegrini conceded.
– Manuel Pellegrini, speaking at the Premier League launch.
"It's not finished, until the last day we can do different things.
"But if you ask me at this moment if I am happy with the squad, yes I am very happy with my squad.
"We had a lot of problems also with Financial Fair Play with the restriction of the amount of players we can put in our squad.
"So maybe I don't think that we are going to sign another player because we cannot do it.
"We have maybe too many players in the squad at this moment, players that need to play, that's very important, especially for young players.
"John Guidetti or maybe Scott Sinclair, they may need to play in a different team, so we'll see from now until the end of the transfer window what happens with our squad.
"But at this moment, yes we have too many players."
Pellegrini has added Bacary Sagna, Fernando, Willy Caballero, Frank Lampard and Bruno Zuculini to the champions' squad, along with Mangala this summer.
City expect to stay within the £49million spending limit imposed by UEFA for last term's FFP breaches, while Pellegrini is also mindful of sticking to the reduced 21-man squad cap.
Feyenoord are understood to be keen on completing a permanent deal for 22-year-old Sweden forward Guidetti, who enjoyed a loan stint with the Dutch club in 2011-12.

Manchester City players Joe Hart, James Milner, Jesús Navas and Stevan Jovetic have unveiled the club's new away kit in Manhattan.
Yaya Toure has vowed to remain at Manchester City as he asked for an end to a summer of speculation largely begun by his own agent.
Toure and his representative Dimitri Seluk confirmed the Ivory Coast international's intention to honour his contract - which runs until 2017 - at the Etihad Stadium.
– Yaya Toure.
"The fans have always been good to me, they've always been good to my family.
"I want to stay. I will always honour my contract. I don't think about all this speculation. It's a big pleasure to stay and enjoy the next season."
Toure's agent Seluk sparked speculation about his future just days after City lifted the Barclays Premier League title - claiming Toure was hurt by the club's failure to mark his birthday - despite a video on the club's website showing Toure being presented with a birthday cake.
Further stories followed as Seluk claimed his client had been shown a lack of respect by City, and he was strongly linked with Paris St Germain before, in recent days, rivals Manchester United emerged as another possible destination.
But Toure described the speculation as "disappointing" as he said he owed a debt to City fans.
"Everything is fine now," he said. "There was a lot of speculation, you know. I think sometimes it's quite disappointing. I need to do something for the fans, it's important to let them know. They've done a lot for me. The team is preparing well and we will try to win again next season."
Seluk, who spoke before Toure, had said: "I would like to say Yaya will stay at City. He won't go to any club. Everybody can stop speculation about this.
"Yaya will stay at Manchester City 100 per cent. He has a contract, he will work very hard and I hope this season he will be the best player in England."
Although Seluk is seen as the source of so much of the speculation - something he has a record for starting most summers, even before Toure signed for City - Toure backed his agent.
"He's quite strong sometimes, but he's a very good guy," he said. "To be honest, we never wanted to talk about money. There are more important things than money. To be happy, healthy. Respect as well is very important."
Seluk was even able to laugh at some of the more surreal stories that have come out in recent weeks.
"I hope now everybody will have a very friendly relationship," he said. "I hope his next birthday they will celebrate together."
Samir Nasri has signed a new five-year deal with Manchester City, the club have announced.
