Croatian midfielder Mateo Kovacic is prepared to spend another season with Dynamo Zagreb in order to continue his development.
The 17-year-old has attracted interest from a host of Europe's elite having already featured for his country's Under-21 side.
However, according to director of sport Zoran Mamic, the club are only likely to listen to offers in the summer.
"The transfer window is quiet at our club at the moment," Mamic told 24sata.
"But nobody knows what the next few days will bring to us.
"The fact is that Manchester City and Tottenham are interested in Mateo Kovacic and they want to buy him right now.
"But even if we would say yes and the deal would go through, he would stay with us until the end of the season."
The starlet himself hopes he can stay in the Croatian capital, saying: "I'm still young and in no hurry. "I believe that it would be good for me if I would stay at Dinamo for one more year and then go out from Croatia."
While City have been mentioned previously with being interested in Kovacic, Tottenham are a new name to enter the fray.
City were said to have begun talks to sign Kovacic last year, while Arsenal and Manchester United were the original suitors for Kovaicic, who just over three years ago was playing for Croatia's Under-14s.
The Old Trafford club were said to be his favoured destination in the winter window, ahead of The Gunners, but news of City and Spurs' admiration could put the buffers on any potential move.
