Torreira likely reaches his top speed quicker than most of them though. Alexis had the same thing. He was never particularly fast but he reached his top speed pretty quickly.
He must be thinking “how the **** are you guys so quick?!”
Acceleration and agility can make you seem much quicker than you are. Whereas if you take longer to reach your top speed (Mustafi, Sokratis etc) or your agility is poor (Xhaka, Holding etc), you're gonna look pretty slow, even if you pick up a lot of steam when you get going.
