It's welcoming if we have indeed bid that much.
I do think it's the exception rather than the rule, in that we're talking about an 18 year old talent who has already proved himself to a large degree, wanted by the best clubs & almost certainly with better years ahead of him too.
Add in the fact that football is going to be on an upwards trend in terms of prices for at least a few years & the signing makes sense across multiple levels, & assuming we didn't have to pay extraordinary wages, would possibly even make more sense as an investment to add to a 'player portfolio' (as I'm convinced FSG view the squad this way) than any other player.
