A swap deal is being mooted which would take Bayern Munich striker Luca Toni to Valencia.
Valencia chiefs are in the market for a major striker signing, but do not have a big budget to play with.
Bayern coach Louis van Gaal has told Toni to find a new club in January after losing patience with the Italian's outspoken manner.
Spox says a swap could be on, with Valencia willing to offer fullback Miguel to Bayern in part-exchange for Toni.
Miguel's agent, Paulo Barbosa, confirmed: "The prospect of an exchange involving Miguel and Toni is a real possibility."
