David Moyes has been appointed Sunderland manager on a four-year deal. The former Everton and Manchester United boss, 53, takes charge at the Stadium of Light after Sam Allardyce left to become England manager. “I have taken over a big British club, with a great support, and I’m looking forward to working in the Premier League again,” said Moyes. The Scot has been out of work since being sacked by Spanish club Real Sociedad in November. Allardyce was confirmed as Roy Hodgson’s successor with the national team on Friday.
