Mikel Arteta insists he knows nothing about Arsenal being involved in a European Super League.
Widespread reports emerged on Sunday claiming that up to 12 clubs – including the Premier League's 'big six' – were set to announce the new competition.
Manchester United, Manchester City, Liverpool, Tottenham, Chelsea and Arsenal are said to have been joined by teams from Italy and Spain in backing the plans.
UEFA issued a strong response condemning the apparent proposals, vowing to do everything in its power to block the move, and its statement was co-signed by the Royal Spanish Football Federation (RFEF), LaLiga, the English Football Association (FA), the Premier League, the Italian Football Federation (FIGC) and Serie A.
European football's governing body also reiterated a threat it has made before, that it would bar clubs from taking part in other competitions, while it also suggested FIFA still plans to ban players from playing at the World Cup if they feature in such a 'Super League'.
Aside from other footballing authorities, the plans have been met with widespread condemnation, but Arteta was not willing to add to the dissenting voices.
Speaking after ninth-placed Arsenal were held to a 1-1 draw with relegation-threatened Fulham in the Premier League on Sunday, Arteta said: "I don't know anything about it.
"I don't know. Once I know every detail and I have all the information then I can evaluate and give you my opinion."
Real Madrid president Florentino Perez is rumoured to be heading up the new league, while the owners of Liverpool, United and Arsenal are reported to be filling vice-chairman roles.
It has been suggested an announcement from the clubs in question could come as early as 21:30 BST on Sunday.
