Graham Potter started his playing career at Birmingham City in 1992
Chelsea have appointed Graham Potter as their new manager following the sacking of Thomas Tuchel.
Potter has left fellow Premier League club Brighton to take up the role and has signed a five-year deal with the Blues.
The 47-year-old said he was “incredibly proud and excited to represent Chelsea”.
Potter’s first game in charge will be an away derby with fellow west London club Fulham on Saturday at 12:30 BST.
“We are thrilled to bring Graham to Chelsea,” said the Stamford Bridge club’s chairman Todd Boehly.
“He is a proven coach and an innovator in the Premier League who fits our vision for the club.
“Not only is he extremely talented on the pitch, he has skills and capabilities that extend beyond the pitch which will make Chelsea a more successful club.
“He has had a major impact at his previous clubs and we look forward to his positive impact at Chelsea.
“We look forward to supporting him, his coaching team and the squad in realising their full potential in the coming months and years.”
Former Ostersunds FK and Swansea manager Potter led Brighton to a ninth-place finish last season, the club’s highest ever top-flight finish.
“I am very excited to partner with Chelsea’s new ownership group and look forward to meeting and working with the exciting group of players and to develop a team and culture that our amazing fans can be proud of,” said Potter.
He also offered a “sincere thanks” to Brighton, including chairman Tony Bloom, for their support during his three-year spell at the club.
Potter’s assistant Billy Reid, first-team coaches Bjorn Hamberg and Bruno, goalkeeping coach Ben Roberts and assistant head of recruitment Kyle Macaulay will join him at the Chelsea.
Brighton Under-21 coach Andrew Crofts has taken over as Brighton’s interim head coach.
“I am very disappointed that Graham will be leaving us,” said Bloom.
“He has done exceptionally well over the past three-and-a-bit seasons, he is an exceptional head coach and an exceptional person. He will be hugely missed at our football club.
“He leaves an excellent legacy for his successor with the club in its highest ever position, and on the back of leading us to our highest finish in the club’s history last season.
“I would like to thank Graham, Billy, Bjorn, Bruno, Ben and Kyle for their work here, and wish them all the very best for the future.
“While our attention is now on appointing Graham’s successor as head coach our immediate focus, of course, is on Saturday’s game at Bournemouth and supporting Andrew Crofts as interim head coach.”
