As one of the BIG 6 in the Premier League, Chelsea has top influence and strength, but unlike the old giants such as Liverpool and Manchester United, some of Chelsea's main achievements have been achieved in this century, and the team's purchasing power has increased rapidly after the consortium has taken over, but throughout the history of Chelsea, there are also many loss-making transactions
Salah 2016 Chelsea → Roma 15 million euros
If you want to list the top stars in today's football, Salah can definitely be among the top, there is no doubt that as the number one star in Africa, the "Egyptian pharaoh" Salah has conquered the hearts of many fans with his superb skills and beautiful goals, but if we turn back the time to eight years ago, when Salah just made a name for himself in Basel, Chelsea shot in time to sign it for 16.5 million, unfortunately, under Mourinho Salah was depressed and could hardly get enough opportunities. After only 19 appearances at Chelsea in two and a half years, in 2016, Salah asked to leave the team, and Chelsea sold it to Roma for 15 million euros, which is when Salah really embarked on the road to stardom
Cuadrado 2017 Chelsea → Juve 20 million euros
In the winter window of 15 years, Chelsea loaned Salah to Fiorentina, and added 31 million euros, signed Brazil's World Cup assist king Quadrado, but chelsea's Colombian winger was completely unable to show his ability, only half a season for the Blues, Cuadrado was loaned to Juve, two years later Juve bought it out for 20 million euros, did not expect to come to Juventus Quadrado to find himself again, play his all-rounder potential, even if he changed to play full-back, Cuadrado also showed top performances, especially last season, Quadrado alone gave 17 assists, it can be said that whether the deal is bought or sold, Chelsea have lost money
Lukaku 2014 Chelsea → Everton 35.4 million euros
If "Warcraft" Drogba is the greatest goalscorer in chelsea's history, then Lukaku can be awarded the title of "Little Monster" by fans is enough to prove the expectations of the outside world, in 2011 Chelsea spent 15 million euros from Anderlecht to sign the 18-year-old Lukaku, but in Chelsea Lukaku did not cash in on talent, but during the loan to West Brom and Everton, there was always a bright play, so in the summer window of 2014, Lukaku's outstanding performance impressed the Everton executives. The latter bought it out for 35.4 million euros, and then whether it was with Manchester United or Inter, Lukaku's transfer fee was not less than 70 million, until last summer window, Chelsea spent 113 million yuan to bring the whirling Lukaku back to Stamford Bridge
De Bruyne 2014 Chelsea → Wolfsburg 22 million euros
As Lukaku's teammate in Belgium, De Bruyne also had a time playing for the Blues. In the winter window of 2012, Chelsea signed 21-year-old De Bruyne from Genk for 8 million euros, and as with Salah, chelsea De Bruyne almost did not get a chance to play, after being loaned to Bremen for a season, de Bruyne returned to Chelsea is still a marginal figure in the team, so in the winter window of 2014, Bundesliga powerhouse Wolfsburg spent 22 million euros to get the Belgian international, and it turned out that Chelsea once again missed a top genius. In the 14/15 season, De Bruyne played 51 games for Wolfsburg, handed over a gorgeous stat of 16 goals and 27 assists, becoming a popular football star in one fell swoop, and was taken away by Manchester City for 76 million euros in the summer window of that year
Robben 2007 Chelsea → Real Madrid 35 million euros
In 2004, Chelsea took a fancy to the main winger Robben of the Eredivisie giants Eindhoven at the time, so he spent 18 million euros in the summer window to bring it in, the deal was very cost-effective, "Peter Pan" only took half a season to conquer the hearts of Stamford Bridge fans, he and Duff even created a two-wing flying precedent, then Chelsea in the domestic arena is more people to block people, Buddha to kill Buddha. However, in 2007, Robben was invited by Real Madrid, the player himself hoped to land at the Bernabeu, and Chelsea, which was pursuing Alves at the time, did not stay, 35 million euros, Real Madrid took away Robben, although robben in white did not meet the expectations of the outside world, but Chelsea, which lost Robben, was still affected
