Sunderland have signed France Under-20 international midfielder El Hadji Ba on a three-year deal.
The 20-year-old was a free agent after leaving Le Havre last month, where he scored once in 13 games.
Ba joins fellow signings Jozy Altidore, David Moberg Karlsson, Cabral, Modibo Diakite, Valentin Roberge and Vito Mannone at the Stadium of Light.
And Velez Sarsfield say left-back Gino Peruzzi is set to meet with Sunderland after the two clubs agreed a deal.
The Argentine club has confirmed on its official website, and say the 21-year-old will travel to England to discuss terms.
