All the latest news, views and transfer rumours from the Etihad…
The former Everton star has been a bit-part player during his time at the Etihad Stadium. But he will now have the chance to fulfil his potential at the Black Cats.
It is a smart piece of business for Gus Poyet’s side, bringing in a player who has much to prove following his disappointing spell in Manchester.
Speaking to the Manchester Evening News, Corrigan said, “It is up to Joe if he keeps his place.
“I think Caballero will push him on. I was fortunate when I was playing to have that competition.
“You knew that if someone else got a run in the team then it would be really hard to get your place back.”
Hart will not want another spell on the bench after being rested in place of Costel Pantilimon in Manuel Pellegrini’s first season in charge.
The former Chelsea star currently has 973 club appearances and will spend time on loan at the Etihad prior to his move to New York City FC next year.
