Seeing Potter's name being tossed around, I really don't like him as a person (think he's two-faced and disingenuous, probably a poor man-manager as well as was shown at Chelsea). But what I will say is that he is a very good coach tactical wise and plays a brand of football that's very pleasing to the eyes.
Also reminds me of Jervis Tetch or The Mad Hatter from the Batman for some reason in his demeanor.
