Pepe also scored 7 goals (as a winger) and had 4 assists last season. Martinez and Pepe are of the same age. Pepe is, unlike Martinez, an international player. Why wouldn't you want to compare the two?
And again you're missing the main point. In time when the Italian football is in crisis, we still proceed with our policy to invest mostly in Italian players (6/8 new players in Juve are Italian). Italian players aren't cheaper than the non-Italians. Quite the contrary, as it's the case with every country, the domestic players are valued higher if they're of the same quality as the foreigners. Pepe being some 1.5m eur cheaper than Martinez isn't because he's Italian, it's because he's the inferior player to Martinez.
