David Moyes', whose contract was set to expire in June, will leave Everton at the end of this season. The club confirmed his departure in a release on their club website, and indicated that Moyes "met Chairman Bill Kenwright early yesterday evening and confirmed his desire to join Manchester United." Because Moyes is out of contract, Manchester United do not have to approach Everton about appointing them if he is their choice, as has been widely reported.
Moyes has refused to sign a new contract with Everton all season, indicating that he might have been willing to look elsewhere for employment even if the Manchester United job had not opened up. Everton have been in a serious financial bind in recent seasons, with Moyes having less money to spend than the team brought in through player sales.
The Manchester United press office tweeted early on Wednesday morning that Moyes had been appointed as United manager, but promptly deleted it. His confirmation has been expected since early on Wednesday, but United have not announced anything yet.
