Take it with a grain of salt—couldn't even read the thing in full as it's partly paywalled—but post-Christmas Kai at 9 is a good answer to our striker problem.
We've got two more pressing areas of weakness: getting a consistent threat out of our left side, and the squad's rapidly obsolescing options to give us progressive passing in the build-up. We need to make good on a few sales, and improve in one or both of these areas—by hook or by crook.
