Luiz Felipe Scolari has been fired as Chelsea manager.
A statement on the club’s official website says the decision was made “to maintain a challenge for the trophies we are still competing for”.
The statement added: “Felipe has brought many positives to the club since he joined, and we all feel a sense of sadness that our relationship has ended so soon.
“Unfortunately the results and performances of the team appeared to be deteriorating at a key time in the season.
“In order to maintain a challenge for the trophies we are still competing for, we felt the only option was to make the change now.
“The search for a new manager has already started, and we hope to have someone in place as soon as possible.”
Assistant coach Ray Wilkins will take over until a replacement is appointed.
