Don't think many would class Mirallas as poor but isn't it a fair criticism to say that Kev's form and fitness is erratic? A lot of wingers are, seems to go with the job description like eccentric is applied to goalkeepers, but it can be very frustrating at times even if overall you appreciate what he brings to the club.
You previously quoted Executioners bong so am guessing you feel he is a pretty rational poster, this is what he wrote today.

Mirallas recent charm offensive about signing a new deal has – probably – been the result of his agent not finding him the ECL suitor his ego appears to crave. Whilst the gold Bentley driving winger is clearly inconsistent (and a bit of a tit) there’s no doubting his capability 1v1; he’s a great finisher, and arguably the best at the club in such scenarios.
