Agree, that's why I'd want that Barca young CB or the like that Five/BC suggest, someone lean powerful, outstanding potential, quick burst pace, fast minded. One who could cover either CB, ideally very early 20's.
Think maybe Kane's said this is his last season if we don't win something, so Levy has decided it's relatively risk free to invest £100M (before later sales), on what his team have agreed are 'commodity quality' as we can recover that from Kane next summer if it fails and striking now we would only need to replace Kane (should the next signing(s) manifest and perform).
