OFFICIAL: Sunderland officially terminate club-record signing's contract
Sunderland served notice on September 12 to terminate Djilobodji's contract after he reported for training several weeks late and 'comprehensively failed' a fitness test.
Sunderland have officially confirmed that they have terminated the contract of their record signing, Papy Djilobodji.
Djilobodji signed for a club-record £13.6m in 2016 but failed to establish himself either at the Stadium of Light or during a loan spell at Watford.
A club statement on Twitter confirmed his departure.
It read: "Sunderland AFC has reached an agreement with Papy Djilobodji for his departure, his employment having terminated on 21 September 2018."
The club will be due compensation if and when Ndong signs for a new club.
Djilobodji made only 24 first-team appearances for the League One outfit following his £8million move from Chelsea in 2016, and spent last season on loan at Dijon.
