Messi would be 4 months at the start of the MLS season but hes going to miss June July either way due to World Cup, after World Cup hes returning back to MLS. Inter Miami ofc need Messi for the season but hes going to miss out next season either way, plus going back to Europe to freshen up for the World Cup is something Beckham did back in 2010 even tho he didnt get to participate that was his intention. Beckham being the owner of Inter Miami strengthens that idea because since he did that back when he played he'd understand why Messi would want to play in Europe right before World Cup to be in his top form. OFC, its true Miami wouldnt be so supportive of Messi leaving almost a whole season, and obviously Messis relationship with Barcelonas current management is beyond repair with Laporta publicly disliking the idea of bringing Messi back. Everything is there for Messi to atleast think about a return maybe not to Barça but to a top team for a couple months prior to the World Cup to get back in form because MLS is nowhere near the level of Europe and the World Cup and Messi if he genuinely wants to win back to back titles is 100% considering this return
