Midfielder Tiago Silva has become Sabri Lamouchi's first signing at Nottingham Forest, joining from Portuguese club Feirense on a two-year deal.
Silva, 26, has left Feirense after they were relegated from the Portuguese Primeira Liga last season.
The midfielder has joined a week after former France international Lamouchi replaced Martin O'Neill as Forest boss.
He is their second signing of the summer, following ex-Bolton winger Sammy Ameobi to the City Ground.
