Pearson was a brilliant manager for us. Took us to two league titles and two promotions and a further two play-off campaigns. He built two seperate great teams, the first one which finally kicked us up the arse after several years of utter misery and one of, if not the, worst few years in the club's history - it was a pretty direct side built around its work rate and fitness which put a passion back into the club that hadn't been there for years. Then his second side, he came in and had to get rid of some of the big egoed, big money, but mediocre Championship players that Sven had spunked money up the wall on and built a really exciting young side which was much more attacking and had more flair than his original side and the spine of that side (Morgan, Drinkwater, Mahrez, Vardy) is still our spine today - I remember when we signed Knockaert, I'd never seen a Leicester player like that before, with that level of skill and artistry - then we signed Mahrez and he was even better.
I was gutted when he left and yes, the spine of the side is still the same, however, that does not mean than Claudio hasn't been the one to push us onto the next level and doesn't deserve enormous credit. He'd made Vardy the figurehead of the attack rather than the support striker he was for Nugent/Ulloa, he's given Mahrez a free-role, he's converted Albrighton to a previously unfamiliar position on the left, he's got the best out of Morgan and Drinkwater and Kante and all those players are having the form of their careers so far.
Saw an interview with Vardy the other day when he said the main thing Claudio has done over Pearson is he's so much more tactically in-depth - under Pearson you'd know you're job and train for it, but under Ranieri you have booklets and loads of video clips every week on the opposition and your own performances and go into far more depth about how you exploit opposition weaknesses and how our players could get working tactically as a team.
Pearson will always be a hero to me and I was gutted when he left, he was fantastic for the club when he was here - a club which as we all remember were ****ing miserable before he came in and yes a lot of the players are still the same so you could call it "his side", but Ranieri has clearly come in and taken that side to the next level with his greater managerial experience and tactical knowledge and he deserves all the credit he gets for where we are in the table.
