Sunderland have confirmed the signings of Modibo Diakite, Valentin Roberge and Adilson Cabral.
The trio all signed deals with the Premier League side earlier this summer but have now officially joined the Wearside club after the transfer window opened today (July 1).
So who are the new boys and what can fans expect to see from them at the Stadium of Light?
Sunderland announced the signing of Modibo Diakite on a free transfer on May 30.
The 26-year-old had been with Italian side Lazio since 2006, but his contract with the Serie A club expired this summer and the Frenchman put to paper on a three-year deal on Wearside.
Diakite is renowned as being a central defender with a strong physical presence.
Another Frenchman to join Paolo Di Canio's side is Valentin Roberge.
The 25-year-old has spent the last three years at Maritimo, and enjoyed relative success during that period with the Portuguese side qualifying for the group stage of the UEFA Europa League last season.
However, the defender's contract expired earlier this summer and he signed a three-year deal with the Black Cats on June 10.
Roberge is primarily a centre-back but can also play on the left side of defence.
Sunderland also announced the signing of midfielder Adilson Cabral on June 10.
The 24-year-old has been among the ranks at FC Basel since 2007, but agreed a three-year deal with the Black Cats after his contract with the Swiss champions expired.
Cabral played for Switzerland at Under-21 level but reverted to his original nationality and made his international debut for Cape Verdi in 2012.
