With Jeffrey Schlupp swapping Leicester for London with his eye-watering £12.5m transfer to Sam Allardyce’s Crystal Palace in the past few days, he becomes the latest in a long line to depart Leicester City for a sizeable fee.

Some supporters were shocked at just how much Claudio Ranieri managed to earn from the sale of the Ghanaian, but it will surely be useful in their dwindling title defence.

As a matter of fact, the Foxes have raked in approximately £70m in the past 20 years alone from sales of players.

However, who actually are the Foxes’ most expensive departures in history?

5 – Neil Lennon to Celtic (£5.75m)

The current manager of Scottish Championship outfit Hibernian, Neil Lennon was one of the first names on the team-sheet under former manager Martin O’Neill.

Under the Northern Irishman, the midfielder made over 200 appearances for the Foxes and scored nine goals.

The Manchester City trainee was a key-cog as the Foxes took home two League Cups in three seasons and secured three consecutive top-ten finishes in the Premier League.

As a matter of fact, the ex-Celtic boss played in the East-Midlanders runs in the UEFA Cup back in 1997 and 2000.

Lennon was widely known for his dogged style of play and his unwavering effort impressed supporters for four seasons following his arrival from Crewe Alexandra.

However, he soon followed former manager O’Neill to Scotland and departed for Celtic Park for a reported £5.75m in 2000.

Since then, Lennon has managed the Hoops and won silverware aplenty in Scotland.

4 -Andrej Kramaric to Hoffenheim (£8m)

Signed in the January transfer window of 2015, from Croatian side HNK Rijeka for an undisclosed fee in the region of £7m, there was hope that Kramaric could power Leicester City to safety under Nigel Pearson.

For the majority of the campaign, the Foxes were rooted to the bottom of the Premier League, only for a miraculous late charge to secure another season of top-flight football.

Scoring three goals in 15 appearances in his debut campaign in England, the Croatian forward gave supporters only a glimpse of his talent.

However, under Claudio Ranieri in the following campaign, the striker only made a further five appearances as the Foxes stormed to the title and was soon shipped out on-loan to Bundesliga club 1889 Hoffenheim.

Netting five times in 15 league appearances, the German outfit soon made the deal permanent in the following summer transfer window for a reported £8m, with Kramaric signing a four-year deal.

3 – Emile Heskey to Liverpool (£11m)

A cult figure at Leicester City and sometimes a figure of fun in the Premier League, Emile Heskey developed a fearsome reputation in his early days at Filbert Street.

Progressing through the youth system at Leicester City, the powerful forward was in the same team as Neil Lennon that lifted two League Cups.

In total, the England international made 197 appearances for the Foxes and scored a respectable 46 goals. In fact, he found himself on the fringes of the national set-up in his time in the East Midlands.

Nonetheless, Anfield then came calling in March 1999. Gerard Houllier secured the deal for Heskey with a then club-record £11m bid and it was tough for then cash-strapped Leicester to refuse.

Whilst on Merseyside, he won an unprecedented treble of UEFA Cup, FA Cup and League Cup, forming a deadly partnership with Michael Owen.

In a 22-year career in football, Heskey has made 786 appearances and has scored 164 goals for the likes of Aston Villa, Birmingham City, Bolton Wanderers, Wigan Athletic and even the Newcastle Jets.

2 – Jeffrey Schlupp to Crystal Palace (£12.5m)

The inspiration for this article, the 24-year-old made a big-money move to Crystal Palace on Friday evening and became Leicester City’s second-most expensive player sale.

Having been at the club since he was 11-years-old, the Ghanaian winger was a permanent feature in the Foxes’ side, since scoring a hat-trick on his debut in the League Cup against Rotherham United back in 2011.

The pacey winger’s time in the East Midlands has been peppered with success. Lifting the Championship and Premier League titles in only three seasons, he will hope to replicate that success at Selhurst Park.

Upon departing the King Power Stadium, the utility man made 149 appearances and scored 15 goals, being named Leicester City’s Young Player of the Season in 2015 and 2016.

However, having only made nine appearances in the current campaign, he hunted for a fresh start away from his boyhood club, earning the Foxes a cool £12.5m.

1 – N’Golo Kante to Chelsea (£32m)

Arguably the most influential player on this list, N’Golo Kante was first signed by Claudio Ranieri for a reported £5.6m from French minnows SM Caen in the summer of 2015.

Slotting seamlessly besides Danny Drinkwater, the Frenchman helped the Foxes to power to an astounding Premier League title.

Known for his enthusiastic style of play, the midfielder became famous for his trademark tackles and interceptions. Affectionately labelled ‘the rash’, Kante was a dominant force against most sides in the English top-flight and was placed in the PFA Team of the Year.

Making 40 appearances in all competitions and scoring a solitary goal, he earned the reputation as one of the best midfielders in Europe and earnt a spot in the France squad for Euro 2016.

As a result, his stay in the East Midlands was going to be a short one. Lodging a £32m bid, Antonio Conte’s Chelsea snapped up the diminutive Kante, breaking a Leicester City record in the process.

The Parisian now looks set to secure a second consecutive Premier League title at Stamford Bridge this season.
