The fact that he made the statement in the first place regardless of his motivations would rather suggest the opposite
Don't get me wrong I don't think the guy is stupid either, but look at the precise things he says basically says the club cannot compete with other clubs in the sense that they can't afford to spend money and make bad moves implying other clubs can spend more heedlessly. I don't believe for a second that's not him saying well Arsene is cautious because he knows whilst the club can spend money, it cannot waste money.
