Midfielder Franck Dja Djedje says he had to leave Chornomorets Odessa and return to France due to concerns over the political instability in Ukraine.
The 27-year-old, the brother of Marseille full-back Brice, joined Chornomorets at the start of last season and has been a regular for them in both the Ukrainian Premier League and the Europa League.
However, the former Nice player last week returned to France, having ended his contract by mutual consent after becoming concerned for his safety amid the escalating conflict between Ukraine and Russia over control of Crimea.
Odessa is located in southern Ukraine, just over 100 miles across the Black Sea from Crimea.
"When I watched the news, it did not reassure me," Dja Djedje told L'Equipe.
"In Odessa, there are lots of pro-Russian sympathisers and sometimes neo-Nazi demonstrations. It is starting to take a different turn.
"I decided to resolve my contract amicably and leave as a free agent."
Dja Djedje was one of five overseas players to leave fifth-placed Chornomorets last week, with the club unable to offer assurances over security.
A statement on the club's website at the time read: "Given the extremely difficult socio-political situation in Ukraine and Odessa, FC Chornomorets were forced to meet the persistent requests of foreign players and their families who are extremely concerned for their safety.
"In this regard, our club decided to terminate the contract by mutual agreement with the following players: Pablo Fontanel, Markus Berger, Anderson Santana, Franck Dja Djedje and Lorenzo Riera.
"FC Chornomorets heartily thank these players for their enormous contribution to the team's successful performance in recent years."
Dja Djedje played in both legs of Chornomorets' Europa League last 32 tie against Lyon last month but has now returned to France and, according to L'Equipe, is training with Nice's reserve team.
He spent just over a season with Les Aiglons before moving to Ukraine, having previously played for Arles, Vannes, Strasbourg, Grenoble, Paris St Germain and Brest.
The Abidjan-born player represented France at every level up to Under-21 but switched allegiance to represent his native Ivory Coast at the 2008 Olympics.
