Chelsea manager Luiz Felipe Scolari has bolstered his squad by signing Brazilian midfielder Mineiro until the end of the season.
The 33-year-old, who has won 24 caps, was a free agent having been released by Hertha Berlin at the end of last season.
Chelsea have been short of defensive midfield cover with Claude Makelele having left the club in the summer and Michael Essien sidelined with a serious knee injury.
"He is a player that I need because I lost Michael Essien for six months. I have one midfielder like him, John Mikel Obi," Scolari told the club's website chelseafc.com.
