Again, of no consequence to Premier League spending and FFP. The article talks of the likes of Helder Costa who joined them in 2016 and Roderick Miranda in 2017. It talks of 12 players joining after the takeover in 2016. Only 4 were Portuguese. So yes, they exploited the relationship between Nuno and Mendes but who wouldn't?
The spending Wolves did in 2022/23 was the concern when they bought Nunes for 45M, Guedes for 27M, Collins for 22M, Kalajdzic for 18M, Hwang for 16M and Lemina for 5M. They ended up getting rid of all but Hwang and Lemina although Guedes and Kalajdzic went on loan.
The point is though, that they saw an issue coming and took action. They were among the favourites to go down when Lopetegui left.
