Joe Hart reportedly fears that he will be forced to leave Manchester City due to the club's pursuit of Barcelona goalkeeper Claudio Bravo.
The England number one was left on the bench for the Citizens' 2-1 victory over Sunderland on the opening day of the Premier League season.
Willy Caballero was given the nod ahead of Hart by new manager Pep Guardiola, who has admitted that the English shot-stopper needs to improve in order to fit into his tactics.
The Spaniard has claimed that Hart remains in his plans, but according to Goal.com, the 29-year-old is worried that his time at the Etihad Stadium is coming to an end.
The report adds that City are confident of landing the signature of Bravo, who is yet to agree a deal but is believed to be keen to join the two-time Premier League champions.
Hart joined the club from Shrewsbury Town in 2006 and has gone on to win two top-flight titles, two League Cups and one FA Cup.
