Herrera leads by example, his tenacity and work rate seeps onto his team mates and they all seem show the same enthusiasm to get the ball back and fight for the cause (last night showed this perfectly).
Fantastic player, always rated him even when the Café was gunning for his blood. Mainly due to the 2 previous managers dropping him for Fellaini, then when he did get 1 game after months on the bench, he'd get slaughtered and benched again because he wasn't in great form or whatever.
You cant sit on the bench for months then be fully game sharp in your first start. His talent has been wasted, we've had a gem this whole time. P.S. if Pogba doesn't get it, Herrera is a no brainer for the arm band.
