West Brom have announced they have sacked striker Nicolas Anelka, citing ''gross misconduct''.
Anelka himself declared on Twitter hours earlier that he had decided to terminate his contract with Albion, a day after it was confirmed neither he nor the Football Association would contest the five-match ban he was handed for his 'quenelle' goal celebration in December.
West Brom responded by issuing a statement themselves, in which they stressed they had yet to receive any formal notification from Anelka or his advisors.
And they subsequently released another statement on Friday night, which said: "Nicolas Anelka's purported termination of his Premier League contract this evening via social media was invalid as this was not conducted under the correct legal process as required by his contract.
"The club considers the conduct of Nicolas Anelka on December 28, coupled with his purported termination on social media this evening, to be gross misconduct.
"As a result the club has tonight written to Nicolas Anelka giving him 14 days' notice of termination as required under his contract."
Anelka was placed under a club suspension by West Brom after his five-match ban was imposed, pending the conclusion of an internal inquiry.
In his announcement on Twitter, the former France international, who turned 35 on Friday, said he was quitting the Baggies due to the unacceptable conditions they were proposing.
He said: ''Following talks between the club and me, propositions were made to me in order to reintegrate me into the squad under certain conditions that I cannot accept.
''Wishing to retain my integrity, I have therefore taken the decision to free myself and put an end to the contract linking me with West Bromwich Albion to 2014, with immediate effect.''
And Albion made reference to this in their second statement on Friday, saying: "The club notes Nicolas Anelka is unwilling to agree to the conditions set by it which may have enabled his suspension to be lifted and for him to resume training.
"These conditions were, firstly, that the club required Nicolas Anelka to apologise to it, its supporters, sponsors and the wider community for the impact and consequences of his gesture made on December 28 and secondly, that he accept a substantial fine."
