Those two are surplus to requirements and should be looking to find new homes by the start of next season (ideally the current season, but we know that isn't going to happen).
I don't really think so. Mostly it's just when papers need to say who our alternatives are, it will go something like "they want one of Lavezzi, Jovetic, Nani" even though we are only reported to be trying for Lavezzi of those three at the moment. Unless you believe we will exchange Vidal for Hernandez, Nani and Valencia
