Paul Lambert has been handed the task of lifting Ipswich Town clear of the Championship's relegation zone.
The 49-year-old, who left Stoke City in May when their relegation from the Premier League was confirmed, has signed a contract that will keep him at Portman Road until the end of the 2020/21 season.
Lambert replaces Paul Hurst, who was axed on Thursday with Town at the foot of the table after winning only one of their first 14 matches of the campaign.
He starred for Celtic and Borussia Dortmund during his playing career as well as making 40 appearances for Scotland.
Lambert has managed Livingston, Wycombe Wanderers, Colchester United, Norwich City, Aston Villa, Blackburn Rovers and Wolves before taking charge at Stoke in January.
He said: "I can't wait to get going and I'll be using all my experience - and give everything I've got for Ipswich Town.
"I know about the history of the club, what a fantastic football club it is and I am proud to be the manager here.
"Obviously it's been a difficult start to the season but to get through this period we need to be pulling together as one - players, staff and supporters.
"I want us to play with tempo, with enthusiasm, with drive. I want the players to enjoy their football and I am relishing the challenge of helping to take this club forward."
