Goater scored twice in the last ever derby against Man Utd at Maine Road this season
Manchester City will allow striker Shaun Goater to leave the club at the end of the season.
The 33-year-old forward at Maine Road in 1998 but has become frustrated at his lack of first-team football this season.
City manager Kevin Keegan wanted to keep Goater at the club but has agreed that he can leave in the summer, a year before his contract expires.
"Shaun is now 33 and he feels that he wants to play - that is his choice and that is the way it had to be," Keegan told the club website.
"I have said on record that I have told Shaun privately that I am very happy for him to see out his contract here.
"But I understand that he wants to play so it is up to me and him to be sensible and see what comes up for him."
Goater joined City from Bristol City for £400,000 and any transfer would involve a sell-on fee.
