Sam Allardyce is the "perfect" man to help steer Sunderland away from relegation, says chairman Ellis Short.
Writing in the matchday programme, Short welcomed Allardyce to the club ahead of the Wear-Tyne derby, the new manager's first home game.
And he has lifted the lid on Allardyce's "meticulous" approach to management.
Short said: "There have been some changes at the club since my last programme notes, primarily our manager resigning. Although it was unexpected, what it has done is allow us to bring in Sam, who is the perfect man for this job.
"Sam is experienced, savvy and he understands what we need to do. He is forward thinking and meticulous in his approach to training and match preparation and will ensure that the team is fit and organised.
"I have no doubt that he will give our players the best possible chance to reach their full potential.
"Everyone at the club is pulling in the same direction to ensure that Sam and the team have exactly what they need to turn the season around."
Allardyce named Paul Bracewell as his new number two this week, with Mark Taylor joining the club as performance director.
