David Moyes has resigned as manager of Sunderland following the club's relegation from the Premier League.
Moyes' side finished bottom of the table after winning just six of their 38 games in a dismal campaign.
Former Everton boss Moyes took charge just last summer in the hope of reviving his career after failed spells at Manchester United and Real Sociedad.

Moyes took the decision to stand down following a meeting with chairman Ellis Short and chief executive Martin Bain.
A statement from Short, published on the club's website, read: "I pursued the services of David Moyes for a considerable period prior to his appointment last summer, which makes the announcement of his departure difficult for everyone concerned.
"Having worked tirelessly throughout the campaign to avoid relegation from the Premier League, David has chosen to leave the club without compensation, which is testament to his character.
"In the days ahead we will take some time for reflection, and then focus on recruitment and pre-season as we prepare for our Championship campaign. We wish David well in the future."
Moyes built his reputation during an 11-year spell in charge of Everton but this is the fourth job he has left in the last four years.
There was also controversy during his time at the Stadium of Light and he was charged by the Football Association after telling BBC reporter Vicki Sparks that she might "get a slap" over her line of questioning during interviews.
Moyes said: "I would like to thank Ellis Short and the board for giving me the opportunity to manage Sunderland and the fans for always being so passionately supportive of their club.
"I wish the players and my successor well in their efforts towards promotion back to the Premier League."
