Let's not go down this route again. Herrera has one good game in the 'midfield destroyer' role and suddenly we don't need a CM
Herrera is a bang average player but even a bang average player who is fit, disciplined and committed can be useful. Clearly Herrera excels when he is asked to stop opponents, but what about the 15/16 team we play twice a season that will sit 10 behind the ball and defend?
Brian Clough once said 'anyone can put their foot through a Picasso, the real skill is in painting one" and I think that clearly applies here! We need an upgrade on Herrera, someone who can get about the pitch AND play forwards passes/contribute goals and assists
In addition to an experienced CM, I would also try and get Rueben Neuves from Wolves. Young lad with loads of potential.
