Pogba is expected to be announced a Juve player once he comes off contract at United tomorrow morning.
Arrivabene said: "How is it going with Paul Pogba? We talk to him and things are going very, very well.
"How was Operation Paul Pogba born? There was this meeting that I mentioned. During this meeting, names were mentioned, including that of (Dusan) Vlahovic. You open a door, you throw in a name, everyone looks at you like you're crazy and then slowly the machine kicks in and you build the operation.
"This is how (the operation) Pogba was born. From a question: 'But why don't we have Pogba?'. Be careful, the idea is not enough: the idea is only a provocation, it must then be put into practice.
"We always have to see if the figures are within our reach, and over time. If the numbers are huge, you have to present the operation in front of the board of directors and you cannot present yourself without figures that make sense. If we are talking about important players, of course."
