This is wheeled out every time a big deal happens and although the market changes and players on average cost more now than previously, overall its never really rung true in the way its used. Remember when 'the market changed when Pogba went back to the mancs' but we still bought Salah after that. The trend will never change imo, the average cost of players will continue to increase, but there will always be overlooked players like Salah who go for a lot less than their true value.
As far as I can see it, we rarely pursue the massive massive players. Van Dijk and Alisson are the only 2 i've seen in a long long time, before them, who was the last player we bought and everyone sat back thinking that's a huge deal and statement of intent? Even going back to Torres, it wasn't massive, a good deal, great potential but many pulled up the fact he wasn't putting up huge numbers in spain
Except it is true, Salah was our record signing, since then every main player we bought has been that and more fabhino was the same amount as Salah, Keita, Allison and VVD were all significantly more. Since Salah's transfer Neymar, Coutinho, Mbappe, Dembele and even 31 year old Ronaldo have gone for over 100M. These are top players as you said but now even decent players are crazy money Lukaku 90M, Kepa 70M, Lemar 60M Mahrez 60M Morata 60M
My point is there wont be many decent players at cheap prices because the top players raise the bar and now every team wants top money for the better players. Werner a player many think we might be after will be at least 50M. This idea that we will be able to find rough gems lying around for peanuts is crazy as soon as we are remotely linked to anyone now the price will rocket, its why agents keep throwing our name around as possible destinations for their client
We all believe we are back at the top of the game again and competing with the Barca's, Madrid's, Utd's, City's and rightly so. The problem with that is we will also be charged the premium they get charged for players they want too.
And to claim Torres wasn't a massive signing is crazy he was our record signing in 2007 and many pundits, fans etc thought we'd massively overspent on him, thankfully they were sooooo wrong but we didn't break that record again until we sold Torres and used the money to buy Suarez and Carroll.
