While he's a decent player, he's not worth the price tag they've put on him. I think our desperation for a midfielder could lead to us overpaying again. That's the situation we've found ourselves in. His stats aren't all that impressive and he's been struggling to get in their team for a long time. If that's due in part to our supposed interest in him, it's not a good sign about his mentality. We don't want to see players wilting when the spotlight is magnified on them.
Not likely, considering the quality of midfielders they keep producing. Herrera is yet to earn a single senior cap for Spain at the age of 24 and he isn't even selected in their squads. Meanwhile younger players than him such as Thiago, Isco and Koke are being played and they've got others in the pipeline. The fact they're ignoring him indicates what level they think he's at.
