And if you look at that move though - Shaqiri out, Havertz in - that's a massively huge improvement on what you can have in your side. And not only will it be an improvement on a hugely talented squad, but it sets the squad up to have a replacement if/when that explosive front 3 gets broken up and one (or more) of them leave/get injured long-term.
To be honest, it doesn't even have to be spent on an 'elite' player. Just one that would be class enough to fit in and bolster that squad.
