Sunderland have completed the signing of Lorient midfielder Didier Ndong for a fee of £13.5m.
Ndong has signed a five-year deal at the Stadium of Light and becomes manager David Moyes' seventh summer signing.
Now the Black Cats manager will hope to get a deal done for former loanee Yann M'Vila, who arrived in England on Wednesday in the hope of completing his move.
If the move is successful, the pairing of M'Vila and Ndong could prove Moyes' first-choice pairing at the heart of his midfield.
