The 35-year-old told The Star-Ledger: "It shouldn't be any politics. It should be the best guy playing. With that, if I'm going at it and I'm giving you my all and I'm healthy and you beat me at it, then that's great for the team.
"Fortunately, I'm so old, I don't care about politics anymore. I don't have to be here. I don't have to come out and take any more paychecks.
"I'm really here because I wanna be here and I want to get back on the field or I just want to be a part of a team again and pass on my knowledge."
Sanchez, who was the starter for the majority of the 2012 season, is guaranteed a salary of $8.25m (£5.3m) in 2013.
