In the last five years the world of football has changed a lot, especially in the financial aspect of the green field.

The financial strength of the best clubs in Europe (English Premier League, Spanish La Liga, French Ligue 1, German Bundesliga, Italian Serie A) has increased significantly due to television broadcasting rights, sponsorship, and various other factors.

The value of player transfers has grown substantially in recent years. Neymar The value of player transfers has grown substantially in recent years. Neymarwith a transfer value of 222 million euros leaving Barcelona to Paris Saint-Germain during the summer of 2017 is a real proof.

Other players like Kylian Mbappe, Ousmane Dembele, Philippe Coutinho, and Cristiano Ronaldo has sold more than 100 million euros.

Indeed, the fantastic price is not arbitrary for some players, although not all of them are considered worthy to get it.

On the other hand, some green grass stars have failed to live up to expectations last season due to poor performance, injuries, lack of flight hours and other reasons that made their transfer value drop within a year since July 1, 2017.

Who are the players whose transfer value has dropped in one year?

1. Yannick Carrasco

Yannick Carrasco is one of the stars in La Liga since moving to Atletico Madrid from Monaco in 2015.

He is an important player for Diego Simeone and played a big role in their success over the past few seasons.

The 24-year-old has scored 23 goals and 12 assists in two and a half years at the club.

Carrasco is part of the Belgium national team which finished third in the 2018 World Cup. However, the Belgian made a surprise departure from Atletico Madrid to the Chinese Super League club Dalian Yifang in the January 2018 transfer window.

The player born in 1993 was valued at 40 million euros before the 2017/18 season began, but the price continued to decline during the season.

The former star of Los Indios is currently worth 22 million euros, which is a 45 percent decline from what happened 12 months ago.

2. Arda Turan

The Turkish midfielder arrived at the Camp Nou in the summer of 2015 for around 35 million euros.

Although he played several parts in his first two seasons at the club, the Turkish national team player failed to perform brilliantly in La Liga under Ernesto Valverde.

Considered surplus to requirements at Camp Nou, he returned to his homeland in Basaksehir, Istanbul, with a two and a half year loan agreement.

The 2017/18 season went from bad to worse for the 31-year-old because he was banned from playing for 16 matches for encouraging and abusing assistant referees during Super League matches.

Its market value has decreased by almost 20 million euros in the past 12 months. Arda Turan is currently only worth 4 million euros, a decrease of 83.3 percent from last July's price of 24 million euros.

3. Karim Benzema

Karim Benzema's nine-year period at the Santiago Bernabeu was phenomenal. The Frenchman has won four Champions League titles, two Spanish La Liga titles, two Copa del Rey titles and more with Real Madrid.

The 30-year-old has scored 192 goals in 413 appearances at Real Madrid so far.

The Real Madrid star is one of the best strikers of all time in La Liga history. However, Benzema has become less productive because of its age.

Benzema has only scored 16 goals in the last two La Liga seasons, compared with a total of 39 goals in the 2014/15 and 2015/16 seasons.

The mediocre 2017/18 season has made its price drop by 20 million euros from 60 million euros to 40 million euros or has decreased 33.3 percent lower than what happened one year ago.

4. Gonzalo Higuain

The Juventus striker was once the third most expensive player in the world when he completed a £ 75.3 million fee when he moved from Napoli to Juventus in 2016.

Higuain scored 36 goals in Serie A during 2015/16, which prompted his move to Juventus.

However, he has not been able to reach 25 goals in his last two seasons in Serie A. The Bianconeri's players will score 24 goals in 2016/17 and 16 goals in 2017/18. Although he was chosen by Sampaoli in the Argentina squad for the 2018 World Cup, he started just one match.

The penggawa who is undergoing medical tests at the San Siro is poor in goals in several tournaments and has to struggle to take chances in front of goal.

As a result, its market value plummeted by 26.7 percent in one year and reduced by 20 million euros from 75 million euros to 55 million euros only.

5. Luis Suarez

Luis Suarez is arguably one of the biggest strikers in this decade. The Uruguayan has been a prolific goalscorer for Barcelona for years.

25 goals in the 2017/18 La Liga season are Suarez's lowest goal counts since his debut campaign in 2014/15.

He has scored 40 league goals in 2015/16 and 29 goals in 2016/17. Although only collecting 25 goals in La Liga this season is not the best condition.

Luis Suarez fought in the Champions League this season with just one goal and three assists from 10 appearances.

Although the former Liverpool player scored twice in the World Cup, he cannot influence the game consistently.

Its value in the transfer market has dropped by 22.2 percent due to inconsistent performance throughout the season and also due to age.

Last year he was priced at 90 million euros to 70 million euros this summer.
