The Blues have suffered a poor domestic campaign and are currently sitting 12th in the table, although their progress in the Europa League has been impressive and fairly smooth.
The Blues put in highly accomplished performances home and away to see of the likes of Wolfsburg and Lille, although a home loss to Russian side Krasnodar was one unfortunate blemish.
They now take on Swiss side Young Boys in their last 32 on Thursday night, but Jagielka says that the team would have preferred to be successful in the league and endure a rocky time in the Europa League instead.
“We would’ve swapped a couple of wins in Europe for some in the league,” said Jagielka.
“We’ve done well, performed well, scored good goals and defended pretty well in the main in the Europa League. But we still need to get back to the Premier League and start picking up some points.”
Chelsea narrowly beat the Blues on Wednesday courtesy of a late Willian strike, bringing an end a run of clean sheets that the side had been desperately craving.
Now, Jagielka says that the upcoming fixture against the Foxes has taken on the same significance that that the trip to Crystal Palace at the end of January had.
“We’re not where we want to be,” Jagielka added.
“Leicester is now looking pretty similar to the Crystal Palace game at the end of last month. It was a very important game and it definitely puts a little bit more added pressure on those games because of how close you are in relation to points to the team you are playing against.”
