The Portuguese giant has admitted to owing a small amount money after making a number of expensive signings, but believes a communication error led to its inclusion.
The capital club side believes that the European governing body released the list before the Oct. 14 deadline and that has meant that the name of last year's Europa League semifinalist has been included.
The 18-time Portuguese champion has admitted owing a minor amount to another club, but club president Luis Godinho Lopes has told of his surprise at the revelations.
"I can't say that I am pleased with the ruckus around this issue," he told reporters. "I was sad to see Sporting's name mentioned, there was a communication error."
The Estadio Jose Alvalade outfit last year posted a loss of 46 million euros after making a number of big-money signings, but claim that the club has paid all its taxes and social security payments.
The club's vice-president Jose Guedes has also confirmed that the club owes no salary payments and reassured his team's fans that the amounts owed were negligible.
"The case is related to payments to football clubs and the sums are really not too big," he said.
