Barcelona coach Ernesto Valverde is baffled by the RFEF's non-EU announcement.
The RFEF announced on Saturday that there would be no restrictions on non-European players in this year's Supercopa.
Valverde appeared perplexed at his pre-match press conference when discussing the statement released by the Spanish federation and is adamant that he or the club were not aware that they would be allowed to play as many non-EU players as they like.
"As for the Supercopa not being a professional competition, I do not know what to tell you," he said.
"I think that Sevilla are professionals and we are professionals.
"With all the trouble we have had this week with non-EU squad members, they could have warned us before."
