Youri Djorkaeff has returned to Bolton to sign a new two-year deal.
The 34-year-old midfielder enjoyed a successful loan spell at the Reebok Stadium last season and helped keep Bolton in the Premiership after arriving from Kaiserslautern in February.
Djorkaeff becomes Bolton's fourth major signing during the close season following the captures of Jay Jay Okocha, Akin Bulent and Delroy Facey.
