Steve Cooper did have the buy-in from senior players at Leicester - including Jamie Vardy - but struggled to convince others in the squad.
The former Nottingham Forest boss was sacked on Sunday after just 15 games at King Power Stadium having replaced Enzo Maresca in the summer.
Maresca won the Championship title with the Foxes last season, taking them back to the Premier League at the first attempt, and was well liked by the team.
He had them well drilled, down to the smallest detail, the plan was clear and concise and some of the players had found it difficult to adapt to Cooper's style, which was less expansive with a desire to move the ball forward quicker.
