Lee Grant has lifted the lid on Sean Dyche's drastic attempts to rid 'poisonous' players from his Burnley squad shortly after taking over.
The 38-year-old goalkeeper, who played at Turf Moor between 2010 and 2013, provided a fascinating insight into Dyche's attempted crackdown on bad influences.
Players were asked to write down the number of team-mates they believed had the potential to stir up negativity, according to Grant, with Dyche then aiming to uncover their identities and sell them.
Dyche's desire to uphold discipline within his ranks at the Lancashire club is no secret - and one of his first tasks after taking up his role in October 2012 was to carry out an in-depth review of his players.
