Joe Hart is set to leave Manchester City and is already attracting interest from clubs in Europe

Manchester City goalkeeper Joe Hart would consider a move abroad to play first-team football this season, according to Sky sources.

Sky sources understand the England international will leave City before the close of the summer transfer window after being left on the substitutes' bench for the opening two matches of the new season by manager Pep Guardiola.

Sevilla and Borussia Dortmund are understood to be interested in Hart, while Everton are also monitoring the 29-year-old's situation with Ronald Koeman keen to strengthen his goalkeeping options before the August 31 deadline.

Hart's future has been in doubt since Saturday after he was overlooked by Guardiola for City's 2-1 opening day victory over Sunderland, with Willy Caballero preferred between the sticks.

Sky sources understand City have since agreed a £17m fee with Barcelona for Chile goalkeeper Claudio Bravo, but a potential move to the Etihad Stadium is currently on hold due to a knee injury sustained by Barca goalkeeper Marc-Andre ter Stegen.

City remain hopeful of completing a deal for Bravo, who featured 32 times for Barcelona last season as they retained their La Liga title.

Sporting director Robert Fernandez has said Bravo will be with Barcelona on Saturday for their La Liga opener against Real Betis, but added "after that, we will see". He went on to say that another keeper will have to come in first if Bravo were to leave.

One possible replacement could be Valencia's Diego Alves. Their sporting director has said they cannot meet the wage demands of Alves and have instructed his agents to find another club.

Hart, who is contracted to City until 2019, was once again watching from the substitutes' bench on Tuesday night as City claimed a 5-0 win over Steaua Bucharest in the first leg of their Champions League qualifier.

He has spent more than a decade at City after joining the club from hometown side Shrewsbury in 2006 and made 347 appearances, helping them win the Premier League title in 2012 and 2014.
