More than 10 men is probably an understatement but that’s expected from Sanji when giving Zoro any praise. This hint almost confirms that Chopper will begin to work on helping Zoro get back on the battlefield in some capacity. Remember, Chopper is the Straw Hat Pirates medical expert for a good reason.
It’s unknown if Chopper’s aid will be enough for Zoro to go up against a big enemy again or if he will assist against the weaker pirates but at least Zoro is coming back. We will likely learn more in One Piece manga chapter 1016, which will be officially released on the 12th of June.
