Pjanic for Ramsey: the swap deal that Juve have offered Barca

Last summer, Barcelona confirmed the signing of Pjanic. Cut to a year later, the player has been unable to fit in to the team as expected and he may well be on his way out of the club.
Juventus, on the other hand, appear to be missing the Bosnian international, and reports state that they would love to have him back. In Turin, at least, there is a lot of expectation that he might return.
Juve have spent a while trying to find the formula to convince Barca. The most recent one to be mulled over, according to 'La Gazzetta dello Sport', is a swap deal. To bring in Pjanic, Juventus would be willing to offer Aaron Ramsey to Barcelona in exchange.
However, this Pjanic-Ramsey swap wouldn't necessarily be simple. The problem is that the two players are on very different salaries, something which could complicate the deal when the time comes to balance the books.
Whatever happens, there is still a lot of the transfer window ahead of them, and Juve know that Barca need to alleviate their wage bill. They will fight till the end to try and get Pjanic wearing black-and-white of Turin once again.
