Ramsey has already made it.
As for Coquelin, Lansbury and Frimpong, I'd say the latter could turn out to be perfect cover for Song, similar build, aggressive, defensive minded and still useful on the ball, but then Coquelin is supposed to be pretty useful in that position too. Lansbury will need Denilson and maybe Diaby to leave to have a shot.
Eastmond wont make it here.
