His behaviour after watching his less talented team mates after they miss a chance or waste a pass would suggest otherwise.
I don't think he is anymore motivated by money than any other player, or else he would stay with us and become our highest paid player.
He is a winner, and he wants to win the biggest trophies.
He is leaving for the very same reason all our other top players leave, which is our lack of ambition.
You say he doesn't stay with a club for more than a few seasons, as a reason for him wanting to leave.
But I think the correlation between our top players leaving and our lack of success on the field, as well as the transfer market, might be a better indicator of why Sanchez won't sign a new contract.
It's not Sanchez, or all the other world class players, that have left, that are problem, it's Wenger and the board.
