Sources told ESPN that Everton are close to appointing a replacement with Premier League experience. The club are considering former Wolves and Tottenham boss Nuno Espirito Santo, now coaching Al Ittihad in Saudi Arabia; former Leeds United coach Marcelo Bielsa; and former Southampton manager Ralph Hasenhuttl.
"Everyone at Everton would like to thank Frank and his coaching staff for their service during what has been a challenging 12 months", the club said in a statement.
"Frank and his team's commitment and dedication have been exemplary throughout their time at the club, but recent results and the current league position meant this difficult decision had to be taken. We wish Frank and all his backroom team well for their future in the game."
Lampard was appointed manager at Goodison Park on Jan. 31, 2022, after the dismissal of Rafa Benitez, and the former Chelsea boss was able to steer the team away from relegation in the final week of the season.
But Everton's performances and results this season have placed the club at risk of relegation from the Premier League for the first time, prompting the club board to fire the 44-year-old.
Everton suffered their sixth Premier League loss in the past seven games with a 2-0 defeat at the hands of West Ham United on Saturday. It followed a demoralising home defeat to Southampton last week that the club's board of directors was advised not to attend because of a "real and credible threat to their safety and security."
They are 19th in the league with 15 points, two points from safety. Their next game is against leaders Arsenal on Feb. 4 before travelling to rivals Liverpool for the Merseyside derby a week later.
Everton announced that assistants Joe Edwards, Paul Clement, Ashley Cole and Chris Jones have also left the club. Alan Kelly will remain as goalkeeping coach.
