A destroyer is what we need more than anything though? Herrera is very dynamic/energetic and operates more like a box to box rather than someone who just stays in his position and sprays passes anyway.
You would be surprised to see how good Vidal is in pure destroyer role which he was at Leverkusen, then played as advanced midfielder and score around 15 goals. Then he started playing box to box and bossing it.
In short, he is a complete midfielder with excellent performance in any role in midfield
