Hazard has accumulated a big amount of wealth during his time at Real Madrid. It would be unwise and disadvantageous for him not to seize the opportunity to play alongside Messi especially with his performance at Real Madrid, it is unlikely that any reputable club would settle for him, especially considering the leverage risk posed by his re-occoring injury. Starting afresh in Inter Miami is not a bad move, provided the terms of his contract are reasonable. In my opinion, it could benefit his career as playing alongside Messi would garner media attention. If he performs well, he could potentially secure a lucrative return to the Premier League, reminiscent of his successful days at Chelsea.
What is clear for Hazard is that there is no other choice but an offer from Miami because his potential in Europe is no longer needed by other clubs. By eating blind wages from Madrid, he should be aware of what Hazard has, showing bad results. The condition of the injury which is detrimental to the club is also the reason for him being sold rather than having to be maintained. Now if he is in Miami it is not certain that he will be able to play optimally and his activities will still be as normal as being on the bench and taking advantage of the club's salary.
