Gervinho has signed a one-year contract extension with Roma, the Serie A club have announced.
Jack Cork wants to open new contract talks with Southampton, but remains focused on establishing his first-team place.
Stephane Sessegnon has been granted a work permit and is free to begin his career at new club West Brom.
The Baggies' club-record signing is now available to make his debut against his former employers Sunderland, at The Hawthorns on Saturday.
Sessegnon, 29, signed a three-year contract on transfer deadline-day after Albion surpassed an undisclosed transfer fee which allowed Shane Long to join from Reading in August 2011.
The availability of the Benin international, who left Paris Saint-Germain in a £6million move to Sunderland in January 2011, will be a big boost to manager Steve Clarke with Republic of Ireland forward Long likely to be missing again with a knee problem.
In his first full season at the Stadium of Light, Sessegnon finished as the club's eight-goal joint-leading scorer.
He managed seven goals in 39 appearances in his second campaign with the Black Cats and has made 40 appearances and scored eight times for Benin and featured in the 2008 and 2010 Africa Cup Of Nations.
In total, Sessegnon has made 294 career league appearances, including 30 as a substitute, scoring 42 goals.
