These guys aren't just freebies, but look at what their club was before Juve:
Barzagli: Wolfsburg
Pirlo: AC Milan
Llorente: Athletic Bilbao
Pogba: Manchester United
Evra: Manchester United
Neto: Fiorentina
Coman: PSG
Khedira: Real Madrid
Dani Alves: Barcelona
5 players are from a topclub, 4 from a subtopclub (Milan included). Beppe has the market on this level in his control, believe me these transfers are amazing. There is no other club in Europe who does so good with low fees. Only Bayern with Lewandowski free and some other lowpriced signings for high quality players.
