If he leaves I'd be surprised if he went for more than 20-25m. Even though there are clubs who would still gladly pay more if Inter demanded it.
I personally, as I wrote earlier, believe that Inter can sell him for at least 30 million euros in the current inflated transfer market. The maximum that I can see him being sold for is 40 million euros but that would almost require more top clubs to be interested in him. So far from what I have read and seen in the media (it changes all the time though) Barça and Liverpool seem to be the most interested clubs out there.
Honestly while Liverpool is a big traditional club they are not going to play in the CL either. Nor would playing time be guaranteed for him there. Then there is adoption. Italy and England are quite different countries, the language barrier, playing style etc.
Of course he could earn more but I hope that he is smarter than that because in his situation playing time is much more important and if he fulfills his talent he should not worry about earning money. Especially when he is this young.
I think that he will stay at Inter for 1 more season at least. Might not be such a bad thing for him. I don't think that he is quite ready for a club like Barça. Inter can't play much worse than they currently do although as we already discussed in the Inter thread there are some doubts about Thohir and Mancini.
Of course Mancini might want to sell him to make room for transfers due to the FFP. Inter seem to really want a 32 year old Yaya past his best. I don't understand such a move if that means that Kovacic will be sold. But OK truth be told Yaya is the better player currently but his age is advanced and he has no resale value and a high salary.
