Koffi Romaric has reacted with anger after Le Mans shunned a bid from Sevilla for his services.
With Christian Poulsen and Seydou Keita looking set to leave Seville this summer, the club made a move for Romaric.
But Le Mans - whose squad is attracting a huge amount of interest with the likes of Yohan Pele, Hasan Yebda and Stephane Sessegnon all linked with moves - have shunned Sevilla's first offer believed to be €7million (£5.6million) as they want €10million (£8million) for their captain.
Romaric, though, insists he will not pay for Le Mans again.
"Three years at Le Mans is enough! I have made my decision, I will leave," he declared.
"The chairman has closed the door to Sevilla, it is his problem - in my mind I have already left.
"On 9th July I will resume training and it will be with Sevilla - they have already given me the pre-season schedule and I will follow it.
"Le Mans, it is over - I am upset because I have always been fair and respected them.
"Maybe they will prevent me from going to Sevilla - but I need another challenge and it will be elsewhere, not in Le Mans - it is very clear I won't be back."
