I reckon its Marv and not Obertan, unfortunately.
Depends, they might see Oba as the right player to sit on the bench covering what they've got instead of Remy who can fetch them £10m and can be spent elsewhere. Don't really know the team that well, but thought they had someone big in that role who's name escapes me, his brother plays for them. Also , Marv is on a pretty penny.
Edit: Ayew.
Son of Abedi Pele, there's a 3rd brother that plays somewhere too IIRC.
Strong footballing genes there.
