Thomas Tuchel was sacked after Chelsea's 1-0 Champions League defeat at Dinamo Zagreb on Tuesday; Brighton boss Graham Potter first met Chelsea owner Todd Boehly for talks on Wednesday; Potter signs five-year deal at Stamford Bridge

Chelsea have announced Graham Potter as their head coach on a five-year contract.

Potter becomes the first managerial appointment of the Todd Boehly era following his summer takeover. The American is still acting as sporting director having moved on director Marina Granovskaia, chairman Bruce Buck and technical and performance advisor Petr Cech in a complete overhaul of Roman Abramovich's trusted staff.

Sky Sports News understands Chelsea have paid Brighton a total of £21.5m in compensation for Potter and the other four members of staff that have followed him to Stamford Bridge.

'We are thrilled to bring Graham to Chelsea," said Boehly after Potter's appointment. "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.
