That is according to one media outlet anyway, who claim that Arsenal, Bayern Munich, Barcelona and now PSG are all keen on the twenty-two year old Everton star.
Onana has long been on the transfer radar, and was clearly the most likely candidate to leave this summer once the season ended and it became obvious players would have to be sold to alleviate the club's continuing financial problems.
However, most of the early transfer speculation centred on Jarrad Branthwaite leaving for Manchester United instead, with an initial bid for the England player having been turned down.
Arsenal emerged as the supposed front-runners with a deal for Onana seemingly in the offering until things appeared to cool off more recently.
Now it seems as though the Gunners are still interested and have been joined by a plethora of top European clubs - from Germany, Spain and now France - also tracking Onana.
The former Lille player has been in excellent form for his country at the European Championships, although Belgium have not been anyway near the form expected of them as a whole.
Onana himself had been quoted making comments that he wanted to use the tournament to showcase his talents and get a move away from Merseyside this summer.
He may well get that chance and indeed it seems highly likely he will still leave Goodison Park, although when and to what club he leaves for, is of course uncertain.
Everton though are not under quite so much financial pressure as they were a month or so ago, with the unexpected sale of Lewis Dobbin to Aston Villa and now the seemingly certain additional transfer of Ben Godfrey abroad having raised a reasonable additional amount of money.
So, it remains to be seen whether there will be as much pressure as previously suggested to get a deal for Onana done before the end of this month. Well, there are two days left to find out.
