Martin Glenn stated: “Sam Allardyce is the right man for the England job. His excellent managerial credentials, including his ability to realise the potential of players and teams, develop a strong team ethos and embrace modern methods that enhance performance, made him the outstanding choice.
“That was underlined when we sat down to talk and we could not help but be energised by his personal perspective on England’s future and how it complemented the extensive work that we are looking to build on at St. George’s Park.
“Dan Ashworth, David Gill and I have carried out a thorough process in the last three weeks and ultimately we could not look beyond Sam as the ideal candidate.”
Sunderland are now expected to appoint David Moyes as his replacement, and the club said: “Sunderland AFC confirms the departure of Sam Allardyce, who takes up the position of England manager with immediate effect.
“The focus of everyone at Sunderland AFC now is on moving forward quickly and decisively, with the appointment of the club’s new manager to be confirmed at the earliest opportunity.”
