Andy Carroll and Samir Nasri will leave West Ham this summer when their contracts expire, the club have confirmed.
Adrian and Spanish striker Toni Martinez are also set to depart as the Hammers part company with more than 10 players.
Midfield duo Moses Makasi and Noha Sylvestre, defenders Vashon Neufville and Josh Pask will also depart, as will scholars Mason Barrett, Kevin Dalipi, Jay Mingi and Odysseas Spyridis.
Joint-Chairmen David Sullivan and David Gold released the following statement, in which they paid tribute to the two long-serving players set to leave.
“Andy and Adrian have both been great servants to West Ham United throughout their time at the Club and we thank them for their loyalty and commitment to the Claret and Blue cause.
“Both have provided us and our fellow supporters with some unforgettable moments, whether they were sensational scissor kicks and unstoppable headers in Andy’s case, or penalty saves and goals in Adrian’s.
“They can both be assured of warm welcomes whenever they return to London Stadium and we wish them, as well as Samir Nasri and the young players whose contracts are up this summer, the very best for their future careers.”
