The Premier League side entered the potential banana skin of a tie on the back of a monumental 6-3 win over Arsenal on Saturday, and managed to transfer their form despite a series of changes to their starting XI.
One man brought in was Edin Dzeko, and the Bosnian ace netted a double to add to Aleksandar Kolarov’s fantastic opening goal.
Leicester pulled one back late on in the second-half courtesy of Lloyd Dyer, but the Sky Blues held form to book their spot in the last four of the competition.
Following the result, Pellegrini praised his team for their attitude and performance:
“Important win. For our team it was important to continue in the Capital One.” He told Sky Sports.
“It was important also after we beat some important teams like Bayern Munich and Arsenal to fight today. It is normal that for Leicester it was a very motivational game and that makes it very difficult to play with these teams in the cup.
“I think it is important to improve in the way that we are playing. It doesn’t matter if we are playing Capital One, if we are playing Premier League or Champions League, we try to play in the same way, changing names but doing the same things.”
The only disappointment for Pellegrini came in the first-half as Pablo Zabaleta limped off.
The Argentine is thought to have suffered a hamstring injury, which will rule him out of the club’s hectic festive schedule, which involves a home tie against second placed Liverpool.
