Yes you do see people blaming Secco for signing Diego and Melo, because they were well overpriced and underperformed. Melo has improved overall but still isn't a €25m player. We are talking about hindsight though, right? 'Quality' is also subjective.
I have a funny feeling we are going back to this 'ambition' thing of yours, where you have to spend money and lots of it or you have no ambition. We could have course spent another €25m each on two players this summer and been 'ambitious', but it would still have involved selling all the players we did in reality, because that's how we balanced the books. We couldn't just add them to our existing squad.
