Trotters boss Sammy Lee has added seven new players to his squad this summer - but wants more width in his team.
He has pinpointed 27-year-old Wilhelmsson - but is at loggerheads with the French outfit over their £2million valuation of the player.
Lee is looking to spend nearer to £1million and Wilhelmsson's agent Fabio Alho told The Sun: "Bolton are one of several clubs that are interested.
"I can't say anymore before the clubs have reached a deal."
