Lyon have released a statement denying that they have reached an agreement with Newcastle for the transfer of Bruno Guimaraes.
It was widely reported on Wednesday that the Magpies had agreed a fee for the Brazilian midfielder, though 90min revealed this was not the case.
Now, Lyon have come out fighting and have released a strongly-worded statement.
"Olympique Lyonnais categorically denies the false information disseminated by many media reporting an agreement between Newcastle and OL for the transfer of Brazilian international midfielder Bruno Guimaraes," the statement read.
"In this transfer window period where the slightest rumour is often presented as reality, Olympique Lyonnais reminds that only information officially released by the club is to be taken into consideration."
Guimaraes has been linked with a move from Lyon all season. Manchester United and Arsenal have been keeping an eye on the midfielder while Juventus have also been rumoured to be watching him.
The Brazil international has been in fine form this term despite Lyon's faltering campaign.
