Since parting ways with the Italian, Leicester have received the ultimate "managerial bump"-they comfortably dispatched Liverpool and Hull City in Premier League play, and then came from behind in their Round of 16 series to eliminate a Sevilla side that sits third in La Liga".
It took the hosts just 27 minutes to take the 1-0 lead and make it 2-2 on aggregate.
Paulo Dybala scored a penalty on the night to separate the sides. Leicester's title wouldn't have been possible without Ranieri, and neither would a run on the continent that could continue with them beating reigning European champions on Tuesday night.
Those closely involved with the club say the good-humoured Shakespeare played a pivotal role behind the scenes during last season's 5,000-1 title success.
But Leicester slumped under Ranieri this season and they were just a point above the bottom three when the club's Thai owners sacked the veteran manager last month.

Jorge Sampaoli is confident his Sevilla side can put recent patchy results behind them to rise to a "historic occasion" against Leicester City.
He has spent seven of the last eight seasons on the Leicester coaching staff.
Three games as Leicester boss - three wins. Mahrez's cross was half-blocked but fell kindly for Marc Albrighton, who finished calmly.
Sevilla had a chance to draw level on aggregate when they were awarded a penalty after a foul by Schmeichel on Vitolo, but Schmeichel atoned by saving Steven N'Zonzi's poor penalty, raising the roof in Leicester as a new chapter is written in their remarkable story.
Sampaoli snarled and raged in his technical area and was clearly unhappy at halftime because his players were sent out early for the second half, with two substitutions made.

MI plays five starters who can all make three-pointers and the team ranks among the top 25 in three-pointers made per game. The Gamecocks outhit the Spartans, as pitchers Wil Crowe and Josh Reagan held Michigan State to just five hits.
But the drama was far from over.
Can Leicester reach the quarter-finals?
There are many reasons for the Leicester revival since the departure of Ranieri, majority psychological, but among the most significant has been the signing in January of Ndidi from Racing Genk.
That has two knock-on effects. We will have plenty of time in the summer to take stock and evaluate things then. But it was Porto defender Maxi Pereira who provided Juventus with an opening. If Sevilla had more of the ball in the second act, however, it would hamstring itself with Samir Nasri's sending-off for two stupid fouls - a needless hack on Wilfred Ndidi and a headbutt on Jamie Vardy.
"For me there is no free game in football, you have to try to win every game you go in to and show that determination and competitiveness and we need to show that in abundance tomorrow night".
