The creative winger looks set to depart the Turkish giants after being ousted from the first team, a decision which he believes to be unwarranted
The Portugal international has been suggested as one of the players the Istanbul giants are keen to sell in the summer as they look to reduce their wage bill after being embroiled in a financial battle.
Quaresma has now revealed that he is training separately from Besiktas' first team and expressed his surprise at the club's handling of his situation.
"The club's approach was wrong, no one has spoken to me," Quaresma told NTV Spor. "I have always tried to have the right approach, but the club did not do the same.
"I have always given my best for the team. The club have embarrassed me. This attitude is shameful, they do not even give me equipment to train. Sometimes, I have to wait 30 minutes to get it."
The 28-year-old winger, who signed for Besiktas in 2010 after an unhappy spell at Inter, has one year left on his contract with the Turkish giants.
