Kranjcar was a regular member of Harry Redknapp's starting XI last year but he has fallen down the pecking order this term, largely due to the improvement of Gareth Bale and the signing of Steven Pienaar.
The winger, who has two years left on his contract, voiced his concern at a lack of first-team football last month, and his agent, Adrian Aliaj, admits he is becoming disheartened with warming the bench at White Hart Lane.
Kranjcar turned down the chance to move to Werder Bremen in January, but may be tempted to move to one of the Serie A giants interested in him this summer if Redknapp cannot give him assurances about his future.
"Niko is not happy with the situation at Tottenham at the moment. He wants to play. It is a shame that a man of Niko's quality is on the bench," Aliaj said. "He is loyal to the club and has a contract but it is difficult for him.
"It can be a problem when a player is not playing. When he is not playing he is not happy. He feels down."
