A proven regular Brazil international will, in all likelihood, demand a higher wage as well as the higher purchase cost.
We would hope the younger lad could himself become a regular international but at less cost to us in the process and with more profit margin in the future.
Yeah you're talking 150k per week instead of 60k/week.
So 42 (+add-ons)+ 37.5 wages over 5 years = 80M
Can't afford to invest 80M on a player from abroad, especially one that has already gone to another country and been far from a success.
Joao Pedro - 25 (+add-ons) + 15= 40.
Half the price, and you have a much lower chance of the player being unsettled in the country, problems with the style of the league, settling with João Pedro.
Maybe they aren't the same quality now, but João Pedro has a much lower risk element added to it...
