The former Premier League champions had a busy summer in 2017. Drinkwater departed to join his former Leicester teammate N'Golo Kante at Chelsea while Ron-Robert Zieler was sold to Bundesliga side Stuttgart after failing to impress at King Power Stadium.
The club signed Adrien Silva and Vicente Iborra to add more steel to the midfield. After managing to keep both Jamie Vardy and Riyad Mahrez, two players who were key in Leicester's title winning season, the Foxes added Nigerian international Kelechi Iheanacho from Manchester City. Harry Maguire joined from Hull City to shore up the defence.
