Brazilian Philippe Coutinho is thought to have gained a Portuguese passport in the last few days through his wife, with Luis Suarez and Lionel Messi already having EU citizenship.

According to Sevilla club statement read: “Sevilla FC is surprised by the RFEF [Spanish football federation]’s statement 24 hours before the Super Cup. “It has stated that as many non-EU players as desired can be registered. In their last notice for the 18-19 season, only three were due to be permitted, without exception.

“The club’s legal department is studying the matter and should FC Barcelona submit a team with more than three non-EU players, it would present possible ground for withdrawal on account an improper line-up.”
