pirlo

xavi was considered a great player for barcelona, but untill the EC 2008, pirlo was clear ahead

he had a platini route, great player that reached his peak in his mid to late 20s

pirlo, who is just a year older, was already considered great in his early 20s at milan was already considered a world class player

both of them are great imho

i can see teams using a variant, the 4 2 2 2, similar to what rb leipzig are doing: using two CAMs like xavi simmons and olmo as winger, but more close to the half spaces than classical winger

or as monaco in 2016/2017 with thomas lemar and bernardo silva implementing similar movements
