Sunderland have completed the signing of Ghana international defender John Mensah from former French champions Lyon, the English side reported.

The 26-year-old becomes manager Steve Bruce's sixth signing of the summer, joining Paulo da Silva, Lee Cattermole, Lorik Cana, Fraizer Campbell and Darren Bent at the Stadium of Light.

Mensah joins on a season-long loan and Sunderland have the option to make the deal permanent at the end of the season.
