Kevin Wimmer is attracting interest from other clubs but Tottenham are pricing the defender out of a move, according to his agent.
Wimmer, 24, was a bit-part player at Spurs last season, making just four league starts despite having signed a new long-term contract following a promising debut campaign in 2015-16.
The Austria international's agent Jurgen Werner claims he is a target for clubs in Germany and Italy but believes Tottenham's valuation -- reported to be £20 million -- is proving a stumbling block.
Werner also said that Spurs still rate Wimmer and put his lack of football last season down to his age.
"They [Tottenham] still see him as a talent," Werner told Spox. "If he remains, he will be a regular in two years' time.
"The top clubs of the Premier League all have more experienced players. John Stones [at Manchester City] is the only regular under 25.
"There was also interest from Germany or Italy but, because of the price, it is difficult for all clubs outside the Premier League."
He added: "We have to wait and see what is happening on the English market."
