But Leicester have won their two games under Shakespeare's stewardship and will attempt to overturn a 2-1 deficit in Tuesday's last 16 second leg at home to Sevilla with confidence fully restored.
The Foxes were 11/4 to progress to the last eight after losing the away leg 2-1 but a dramatic 2-0 victory at the King Power Stadium ensures their dream run continues. A late goal sent the Foxes back home for the second leg feeling pretty good, but that was only possible because of the work Schmeichel did earlier, saving a penalty and repeatedly denying a dominant Sevilla team.
Leicester City: Kasper Schmeichel; Christian Fuchs, Robert Huth, Wes Morgan, Danny Simpson; Marc Albrighton, Danny Drinkwater, Wilfred Ndidi, Riyad Mahrez (Thomas Partey 89'); Jamie Vardy, Shinji Okazaki (Islam Slimani 64'). Here, we look at the new boss and how the hosts can reach the quarter finals.
True, they did manage to win their next two league games, overcoming local rivals Real Betis and Athletic Bilbao with hard-earned single-goal victories, but neither performance was convincing and they were slightly fortunate to come away with six points.More news: On visit with Steelers, Davon House signs with Packers
Leicester vs Sevilla is set to begin at 8.45pm CET, 7.45pm GMT, 2.45pm ET, 1.15am IST. Vardy sprinted 30 yards to close down Nicolas Pareja, with the Leicester striker sliding across the turf to make a challenge that was met with huge roars. It was also his risky free kick played to the back post that led to Wes Morgan's opening goal.

But Leicester's players and fans have been universally supportive, while Shakespeare himself has been sanguine.
Rather than a sign of decline, Sevilla's recent results are more likely to be an indication that they have relaxed their focus and briefly taken their eye off the ball. "We need to show all the qualities that have helped us go head to head with Barcelona and Madrid in Spain and to compete in Europe as we have done over the years", Sampaoli said. After all, Shakespeare has all but brought back the Leicester of last season and that's a hell of a story. The new manager admitted he did not expect to be taking charge of a Champions League knockout game in his first match as a full-time manager but there is nothing to suggest he will not get the best out of the players. Manager Jorge Sampaoli was also ejected later in the half. But the Danish keeper was up to task, smothering N'Zonzi's rather weak attempt.
