Ederson out for eight months
Lyon are to look to the transfer market after it was confirmed Ederson will miss several months - and potentially the entire season - with a ruptured hamstring.
The Brazilian midfielder has been ruled out for between three and eight months.
"It's a big blow for him, because he had a very good pre-season," coach Claude Puel said. "This injury is very rare, it is difficult.
"We will see what opportunities arise, and if there is one before the end of the transfer window."
