Raheem Sterling is considering his future at Manchester City over management's actions this summer.
The Mirror says City could have scuppered their bid to convince Sterling to sign a new contract by offering England's Euro star as a makeweight for Harry Kane.
Sterling, 26, was open to talks about an extended deal at the Etihad - despite becoming frustrated by his lack of game-time under Pep Guardiola towards the end of the season.
But the winger is angry with City's attempts to offer him to Tottenham in part-exchange for Kane in a deal that would meet the London club's £100million-plus valuation of the England captain.
The Premier League champions have included Sterling on a list of players they would be willing to include in a bid to take Kane to the Etihad.
But Spurs have remained steadfast in their stance that their striker will not be a replacement for Sergio Aguero.
Sterling has two years left on his current £300,000-a-week contract in Manchester.
