Lyon defender Jean-Alain Boumsong has sung the praises of possible target Patrick Vieira.
The former Arsenal ace has been strongly linked with a move to the deposed French champions this summer following an injury hit season with Inter Milan.
His possible acquisition would be a big hit with former Newcastle defender Boumsong, who believes the ex-France skipper would bring a great deal to the team.
He said: "He could contribute a great deal to the club and fill the gap left by the departure of Juninho.
"He has been captain of France and the experience and the aura he radiates could only add value to our team."
However, Lyon boss Claude Puel has indicated the priority now is for more attacking power by approaching Toulouse about striker Andre-Pierre Gignac, the league's top goalscorer last season.
"The player is interested and is aware that we have made an offer to Toulouse, so the ball is in his court," said Puel.
He added the 23-year-old, who scored 24 times for his club last term, 'has the right profile and is a very good footballer'.
