Yeah, my bad, I thought Juve but wrote Inter. #Brainfartmoments
I'm not saying the position can't be universal, I'm saying one of the reasons he was so succesful at Juve could be that he can highlight exactly the type of players Juve needs, Naingolaan is a far different player compared with Carrick, Kante is a different player than fabinho, but they all play as DM's.
Just walking into a new club, before knowing; the complete philosophy, playing style, weaknesses, strengths & team selections etc. then bringing your own shortlisted players and advising to buy them in the same window could be dangerous.
