After he played well and got the trophy world cup, many clubs want his service now, I do not doubt when PSG and Man City scramble for him, but when I heard the other news, Chelsea have a 200 Million budget to recruit Enzo to Stanford. Of course, when heard that money, Benfica will make 10x profit. Benfica just bought Enzo for 16 million from River Plate, if 200 million happens, the club will be got a lot of money and can build a better team than before.
It looks like Enzo Fernandez's price of up to 200 million euros will not happen, considering that there are two players whose market value has skyrocketed lately Mbappe with 180 million euros and Haaland 170 million euros. Of course, the two clubs don't want a player whose transfer value exceeds their flagship player.
I don't know why you can link him to Manchester City or PSG lol, because Manchester City already have Haaland which is a monster while PSG already have 3 musketeers that wouldn't be replaced as long as they're not injured.
Actually there's a news where mention Enzo Fernandez would move to Liverpool [1], the reason why Liverpool would sign Fernandez is they're lack of strikers right now. Their best strikers: Luis Diaz, Roberto Firmino, and Diogo Jota are injured, so they only have Salah and Nunez. Liverpool need to find a new strikers ASAP since they have FA Cup, Premier League and Champions League.
It seems you misunderstood the position of Enzo Fernandez, he is a central midfielder, not a striker. So yes, it's only natural if I link him (Enzo) to PSG or Man City, I might say because he has compatriots at each of these clubs, so teamwork will be easier. I know that at the beginning this news was very related to Liverpool, but I'm not sure he will join Liverpool, considering Liverpool's performance has been so bad this season and of course maybe Enzo Fernandez will choose to join a club that will clearly win the league competition.
