La Liga chiefs spoke to the flea's father, Jorge, and told him they had received all the necessary documents for the Argentine's return. All permits will arrive by Monday, according to Spanish journalist Gerard Moreno.

Jorge has told La Liga that Messi wants Barcelona and the deal to be closed quickly with 100% security, Moreno says. The move is "80 percent that it happens," according to the Spanish journalist, who adds that all final approvals will be received by Monday. The biggest comeback in world football will take shape next week.
