Maro Itoje says playing for England is "the Mecca" for him and his team-mates after reports a rebel breakaway league is attempting to sign up the game's superstars.
The Rugby Football Union (RFU) has a policy of only selecting players for the national team from English clubs, meaning joining any global start-up competition would put a Test career on hold.
"I don't really know any of the details of it as yet, but wearing this rose is extremely important to me and my team-mates," said Itoje, who added that he first heard of a potential breakaway league via media reports.
"Playing for England is the Mecca."
In October, second row Itoje was announced among a group of players to sign a landmark Elite Player Squad contract with the RFU, giving the national team greater control over their preparation and conditioning.
The 30-year-old also agreed a new long-term deal with Saracens in January and was named captain of the club at the start of this season.
According to the Times, the proposed new league would consist of eight men’s franchise teams, playing a 14-round globe-trotting season, with each set of games being held in a different city.
