Juve won't sell Vidal surely, he's been brilliant this Season.
Anyways I think what the article is trying to say is that the proposed €30M raised from selling Vidal would be moved towards the transfer of Suarez. As in they have X amount of cash ready but would need the futher €30M to meet his valuation?
Well the articles before were suggesting €30M as the fee as well, so I actually think that's how much they think he'll go for, just because the lure of the mighty Juve will be too much for us.
