Defender Winston Reid has signed a new long-term contract with West Ham which commits him until the summer of 2021.
Blackburn have signed defender Doneil Henry on a month's loan from West Ham.
Marek Hamsik insists he is not leaving Napoli this summer.
The Slovakian playmaker is a reported target of Chelsea, Manchester City and Paris St Germain, but the 24-year-old has reiterated he is going nowhere.
Hamsik is under contract with Napoli until June 2016.
"My desire is to remain and win with the Napoli jersey," Hamsik said to Italian newspaper Il Mattino.
Reports in Italy claimed Hamsik, who has scored nine goals in 36 league appearances for Napoli, could leave the San Paolo stadium this summer if his club fail to qualify for the Champions League next season.
Napoli are three points behind Udinese, who hold the last Champions League qualifying spot heading into the final weekend in Serie A.
The Naples outfit must beat Siena and hope Udinese lose and Lazio fail to win their respective games in order to finish in the vital third position.
