Nothing against this type of signing in general, 15 mil. isnt much in today`s marker, actually its even crazy saying that. In worst case scenario, he will fail with us and we can sell him somewhere else for X amount (sadly we all know of our superpower of not getting much in plus when reselling players)
My issue is, this type of signing mixed with us as football club. To explain better, few nights ago during CL game vs Barca, i saw many posts roasting Coutinho and that reminded me of his price, how much Liverpool spent, it was 13 mil. of something dunno was it euros or pounds and they sold him for 10 times more but for that they actually improved him as a player or gave him platform to improve and raised his value for X times, so when Barca wanted him, they had to pay almost 10 times more.
So back to us, since SAF, when was the last time we done something similar and thats where lies my issue with this type of singing at the moment. In our current state we are able to drop level of performances of best players on the planet if they would join us tomorrow.
