Barcelona are confident Dani Alves will remain at the club beyond the end of the season.
Aston Villa boss Tim Sherwood has urged Christian Benteke to follow Fabian Delph's lead and commit his future to the club.
The 28-year-old joined the Blues from Aston Villa in 2010 in a £26million deal that saw Stephen Ireland go the other way, and has helped them to four trophies after going without silverware at his previous clubs Leeds, Newcastle as well as Villa.
But despite securing his second Premier League title with the Citizens, he admits there is some uncertainty of his future given the time left on his current City deal.
"Who knows?" he said. "I have got one year left on my contract. We have won two trophies this year. I have been at the club four years now and enjoyed every minute.
"We have managed to win a few trophies along the way and that is why I came here, to win trophies. That's amazing. I just want to contribute as much as we can and play as many games as I can, and help the club to win trophies."
The Yorkshireman, named in England's squad for next month's World Cup, is keen to help his side successful defend their title but is fully aware of how difficult that task will be.
The Blues fell a long way short of hanging on to their crown in the 2012-13 season, with then-manager Roberto Mancini leaving the club 12 months after he had guided the Blues to their first championship in 44 years.
"It'll be nice to defend it next year. We know how hard it is to win, and even harder to defend. First of all we have to enjoy it. These days don't come along too often."
Captain Vincent Kompany has also promised to bring more silverware to the Etihad.
Thousands of supporters filled Manchester's Albert Square and then lined surrounding streets as the team began an open-top bus tour from outside the town hall to celebrate their Premier League triumph.
Kompany, who scored the second goal in the 2-0 win over the Hammers, said: "This is a team that is growing and we have done it in style.
"Everyone keeps saying, 'They have won the league and they have done it in style'.
"That is what I like about it. That is what I want us to do again in future, keep winning in style.
"We never gave up, we always believe. Together we did it, we knew we could, and until the end we fought and we brought the Premier League back to the city, and in the colours, it should always be."
Playmaker Samir Nasri, who opened the scoring in the final game, paid tribute to the influence of manager Manuel Pellegrini, who made a huge impact in his first season in England.
Nasri said: "Do you want me to be honest? The atmosphere, the manager and the confidence. That is the difference between last year and this year.
"He trusts the players. The philosophy we played all season is just about all the quality we have in this team, that is the big difference."
Keeper Joe Hart, who was named in England's World Cup squad earlier in the afternoon, admitted the season had been a rocky one at times, but he was delighted with his form at the conclusion after a spell on the bench.
Hart said: "It has been a good season, a tough season, but one I have enjoyed.
"It was difficult for me personally but the beauty of this team is that we have got people who can fill in at any time.
"Costel (Pantilimon) was absolutely fantastic when he played, I got taken out of the team.
"He's been brilliant, a pleasure to work with, the same as Richard Wright, and Xabi (Mancisidor) has come in and been a great coach. As a goalkeeping unit we are really blessed at this club and I am proud to be part of it."
