#7 Rob Holding: -€6M
Rob Holding is sadly the case of a Premier League player who cannot get his chances and make good of his case. Holding started the season on the bench in Arsenal's poor opener against Brentford in the Premier League.
Holding then started the next two losses, and the team's overall poor defensive display resulted from his poor performance.
Since those couple of defeats, Holding has made just one more substitute appearance in the Premier League. He has been a regular in the EFL Cup, but that has been all about it as he has played just 547 minutes despite being available.
Holding's valuation has plummeted to €12 million and is unlikely to go up anytime soon unless things change radically.
#6 Tanguy Ndombele: -€7M
Tanguy Ndombele is a classic example of a talented footballer being unable to settle down in a new league or club. He joined Tottenham from Lyon and was expected to be the midfield maestro in the years to come.
However, things have gone in the exact opposite direction as Ndombele has been unable to become a guaranteed starter after failing to display consistency.
Compared to the previous season, Ndombele has secured a few more minutes. But 762 minutes spread across 13 appearances hardly does justice to his ability. He has not contributed much with just three goal involvements, and his valuation has now come down to €38 million.
#5 Cristiano Ronaldo: -€10M
After years of speculation, Cristiano Ronaldo is back at Old Trafford, much to the delight of the fans. He was strongly linked with a switch to Manchester City, but it was with their neighbors that Ronaldo signed for.
He was brought in for goals, and he has provided the club with exactly that. Ronaldo has scored 13 goals and made two assists in 18 appearances for Manchester United so far.
As strange as the reduction in value seems, Ronaldo is 36 and market valuations take the age of a footballer's into account. Ronaldo's valuation of €35 million is still one of the highest among footballers at a similar stage in their careers.
#4 Pierre Emerick Aubameyang: -€10M
Since his last contract renewal, it has been some fall from grace for Arsenal forward Pierre-Emerick Aubameyang. The Gabonese forward has been a shadow of his former self and his poor performances have contributed to Arsenal's struggles in recent times.
Although Aubameyang has been better this time around than last season, it's still far off his standards.
Aubameyang has scored seven goals in 15 appearances this season, but that's primarily due to an EFL Cup hat-trick. He has managed only four goals in 14 Premier League appearances and is now embroiled in a controversy that has kept him out of Arsenal's last four games.
With one and half years left on his contract and an increasing age, Aubameyang is valued at only €15 million.
