City were rocked earlier this summer when their talismanic striker revealed that he was looking to leave.
The Blues had fended off a similar announcement last season and believed that their South American star was settled at Eastlands.
Speculation has suggested that Tevez is a target for a number of clubs, but no deal has been done as yet.
He remains in England as a result and has been included in Roberto Mancini's first-team plans this term.
City believe Tevez will now see out the season on their books, with there few clubs capable of meeting their asking price.
Aguero is keen to see his countryman stay, allowing the pair to work on a strike partnership that could prove to be destructive at domestic and international level.
"We have spent a lot of time together and we talk about everything," Aguero told Sky Sports News HD.
"I know he is a bit frustrated but, as we all know, it is up to the coach to decide who plays and who doesn't.
"I'm sure we will both have a chance here at City and with Argentina.
"I hope he stays and we get to play many games together. But it is up to Roberto Mancini to make that decision."
Aguero was on target for City in their 5-1 mauling of Tottenham on Sunday, taking his tally to three in as many games, but the former Atletico Madrid frontman claims he is still getting to grips with life in the Premier League.
He added: "I was shocked by the pace of the Premier League, it has been a real surprise and I have to adapt to it quickly.
"In Spain, the game is much more stop-start and here it is the opposite - it is very fast, very pacey and very exciting.
"I have been welcomed very much by my team-mates and I hope I can repay the trust that everyone has put in me."
