Arsenal are "privileged" to have Alexis Sanchez and Mesut Ozil in their squad, says team-mate Nacho Monreal.
The Gunners have been in talks with the influential duo over extending their contracts at the Emirates Stadium, with the pair's current deals expiring in 2018.
Manager Arsene Wenger refused to give assurances over their futures at a news conference on Thursday, though, with Sanchez reported to be the subject of a big-money offer to play in China.
And Monreal highlighted the traits that make the Chile star and Ozil so important to Arsenal.
"Both Alexis and Mesut have been around in football for a long time now," Monreal Arsenal's official website.
