The chance to return to the Premier League is almost non-existent. How should he even perform such that teams from the Premier League decide to hire him back to England when in fact he will still be prone to injuries and has only proven his performances in a league that is inferior to the EPL? I think it would be good for him to also have a goal to look forward to that doesn't put as much pressure on him like an engagement with Real Madrid. But I wouldn't underestimate the medical checks here as Inter Miami will also do their thorough due diligence before they sign him. If there are signs that his injuries aren't fully cured or that he could potentially be injured very soon again, I am not sure yet whether that transfer will work out in the end.
Hazard is injured too often, and that must be considered by Inter Miami if you want to sign him. after Messi and Busquets were successfully brought in, now Hazard is a player that is being targeted. but we know how he gets injured very often. and even then it can be a loss for the team if it happens too often.
but pairing Hazard with Messi seems like a good strategy. this might work to change the team to dominate this season. because I'm not sure Hazard will be able to play consistently for several seasons. because he is very often to injury.
As Messi has said before in an interview there is less pressure to play for Inter Miami than there is to play for PSH who wants to win the Champions League or to play for Barcelona or Madrid. Injuries will come no matter what when a player is prone to being injured, but maybe with less pressure on his shoulders Hazard is able to play a good season and can also more control the physical stress when he feels it could be too much for his body. You can't just say that you need a break every now and then when you play for Real Madrid, but that might be slightly different and easier when he plays for Miami.
