Kranevitter, Quintero, Muslera, sometimes Neves if I can afford the clause.
Kranevitter is super cheap and develops great quickly in just 1 season.
Neves becomes great captain.
Quintero gives me go-to free kick taker for next 10 years.
Muslera - really cheap to get, after about 6 months he gets excellent stat spread and sorts the goalkeeper situation for 5-7 seasons until I can get decent regen.
