I don't think Berge's a patch on a 35 year old Fernandinho.
Has he even played much recently? Doesn't seem to have many appearances this season.
Honestly don't know enough about him, but at the age profile and assumed price (obviously if any interest is actually true) it sounds like a cover/squad option at a reasonable price with PL experience abd a decent return resale value, until either an academy player comes into the fold or another target becomes available. In some ways, that option probably also exists with luiz' buy back.
