I do trust our scouts (I don’t play FM anymore so my international football knowledge is poor these days). And I’ve not said I want “proven PL player”. I just don’t reckon a 24yr old doing ok In a poor Portuguese team/league is going to be any better than Costa/Jota/Cav who are all cheaper, younger and better CVs.
Now just off the top of my head, I’d rather we sign Lozano who isn’t “proven PL” but has a solid CV and wouldn’t be that much more expensive. (Now please don’t go into the intricacies - “PSV wont sell him”, “he wouldn’t come” etc. I’m just using this as an example to say we can spend a bit more money and get someone who I’m more confident will improve the first team.
