Keep in mind Transfermarket is nothing, is only a fansite, they have no inside information nor bookmakers' info.
It is just based on some people reading rumors on Twitter.
Its still based off collective rumours on the internet so good chances that it could be correct at some information ( or close to it ) though its not really as accurate as what Fabrizio tweeted or stuff like that. Pretty much a good site for someone that doesnt really have any information about any transfer rumours or speculation to start with
Take Nunez at Liverpool for example or Ronaldo at United.
Pretty sure that Nunez will be back on playing as Klopp need to try things out or else they might keep on losing. As for Ronaldo, I dont see him playing ever as a starter for some time even in Europa League though as Ten Hag is pretty strict when it comes to disciplinary action.
