He didn't sell the grounds (Lyon being by the way the only French club owning its stadium) but the arena that the OL group had just finished building nearby. Many people here fear that the stadium will follow soon.As stated by me earlier, he did sell Lyons ground albeit to the long time family ownership (they'd had it 37 years) so into safe hands.
Btw, I'd be very worried about losing Glasner to us mate, Textor is on record about being a long time admirer of him and looks like you aren't backing him in any substantial way - plus that short term contract is not good for you.
