On the Barcelona end, the club is in clear need of a rebuild that might take a few years, a few years a 33-year-old Lionel Messi does not have. The Argentine legend will not want to end his career in a whimper as Barcelona prepares for a much-needed rebuild, which means he might seek an exit. The other side is, for the first time in history, Barcelona may actually be considering the sale of Messi. It sounds unthinkable, but not really when you consider that the club is entirely too dependent on him, and that prevents any real rebuild.
Think about it, with Lionel Messi at his creative best with 33 goals and 26 assists in just 45 games, Barcelona ended up with ZERO trophies for the first time in 12 years. And as mentioned, Messi's presence on the field did not prevent an 8-2 loss, or the comeback loss to Liverpool last season, and at the hands of Roma the year before that.
