Galatasaray have failed in their appeal to have a ban from European football overturned.
The Turkish club turned to the Court of Arbitration for Sport (CAS) in the hope of getting the suspension – to apply in the next UEFA club competition for which they qualify in the next two seasons – lifted, having been penalised for breaching Financial Fair Play regulations.
However, their appeal was rejected and Galatasaray will not be able to take their place in next season s Europa League.
They had qualified courtesy of winning the Turkish Cup, but, despite seeing the sentence earlier reduced by a year, the ban will stand.
On Thursday, a CAS statement read: The CAS Panel in charge of this matter has dismissed the appeal and has confirmed that the UEFA Club Licensing and Financial Fair-play Regulations had been properly applied by the UEFA CFCB Adjudication Chamber in the present case.
Galatasaray endured a disappointing campaign in 2015-16, dropping to sixth in their unsuccessful Super Lig title defence.
