Sevilla have threatened to back out of the Super Cup tie, Sunday, with Barcelona if the La Liga champions field more than three non-EU players.
The Spanish football federation (RFEF) had earlier said there would be limitations on players outside the EU for the Super Cup.
According to a statement by the team on Sunday, they might pull out of the game in Morocco if Barca make an “improper lineup.”
“Sevilla FC is surprised by the RFEF’s announcement 24 hours before the Super Cup,” Sevilla said.
“It has said that as many non-EU players as desired can be registered. In their last statement for the 2018-2019 season, only three were due to be allowed, without exception.
“The club’s legal department is studying the matter and should FC Barcelona line up with more than three non-EU players, it would present [the] possible ground for withdrawal due to an improper line-up.”
New players Malcom, Arturo Vidal and Arthur will likely be Barca’s three non-EU players on Sunday, even as the Brazilian centre-back Marlon travelled with the squad.
