I'll continue to treat it for what it is: a rumour.
And how many "confirmed" rumours have there been over the years that turned out to be incorrect?
As for how I personally feel about that rumour: not true. If you look at how we operated these last 3 years & think about it logically, then how much chance is there that we indeed offered 30m?
15m + another player? 5m for a loan + 12m for the right to buy + a player? 12m for a co-own? All "reasonable" ideas to come up with. 30m in cash? Not so much.
On a somewhat related note: I'd very much like to see Jovetic at Juve. At the right cost
