Absolutely correct. In actual fact, City will keep it that way until Messi and his dad tell us the next lay of the land.
There is no need for City to even confirm an interest when it could still go legal. The last thing we want is a tribunal deciding to add an extra £50m because we have confirmed an agreement with the player.
On the offering of players and cash, again, see above. City have made it very clear off the record that Jesus and Bernardo are not for sale.
Messi has filmed his stuff with an Argentine unit, no idea who they are.
