It seems like this news might be true, Fenerbahçe president Ali Koç and Hakan Çalhanoğlu reportedly had a phone call and Ali Koç asked about the conditions for a potential transfer.
In the news I read today, Hakan allegedly told Ali Koç:
"We spoke with Galatasaray for a month and a half. Every morning we wake up to Osimhen, every night we go to bed with Osimhen. They pushed me into the background. Even if they try to step in now, I’ll stand firm and come to Fenerbahçe."
So, there's a real possibility that Hakan Çalhanoğlu could join Fenerbahçe.
As for Galatasaray, Osimhen clearly seems more important to Galatasaray and in my opinion, they’re doing the right thing by waiting for him.
This is good news for us then but I hope we can convince Inter to drop to a more feasible level when it comes to the transfer fee. I don't think Hakan Çalhanoğlu is worth giving €30m at this age.

I agree with you. Spending €30 million on Hakan Çalhanoğlu is totally unnecessary, you could bring in young talents instead.
To be honest, I've never really been a fan of Hakan and I wouldn’t want him at Galatasaray either.
I don’t think he has anything to offer our football. These are just my personal thoughts, also I’ve never seen him as a top-level player.
Our big teams should focus on young talents.
Spending 30 million on Hakan Çalhanoğlu seems a bit unnecessary. Better prices should be considered. The club is already deeply in debt, and there's no need to pay so much. Fenerbahçe is also interested, and Fenerbahçe might be a bit more demanding in signing Hakan Çalhanoğlu. Hakan Çalhanoğlu has always been well-known at Inter, and the club wants him to stay.
Still, there are offers coming in for Hakan, not just from Türkiye, but also from the Saudi Arabian League. I wasn't aware of any legal claims. Perhaps the club might act on these claims in the future.
