Celtic look set to be kept waiting for a Moussa Dembele windfall after Lyon boss Sylvinho slapped a final not for sale sign on the striker.
The former Hoops hitman has been strongly linked with a move to Manchester United after an impressive 20-goals season in France, following his £19.7 million transfer from Celtic last summer.
Any future move would net the Parkhead club a tidy sum after they negotiated a sell-on clause.
Dembele himself insisted he was only concentrating on playing for Lyon this season, after the weekend friendly with Arsenal where he scored a brace.
And his manager Sylvinho has firmly closed the door on any future move this season for Dembele.
He said: "Moussa Dembele does not move, for us the window is closed. OK?
"We have a strong squad and a good team.
"I do not know if we will add some players, but even if we don't I am very satisfied with the squad we have at the moment."
Dembele netted 51 goals for Celtic in 69 starts in all competitions in a two-year stint at the champions before leaving for Lyon on deadline day last summer.
United look set to lose Romelu Lukaku in the coming days or weeks leaving Ole Gunnar Solskjaer in need of new fire power.
