Kevin Wimmer's agent Jurgen Werner has claimed that Tottenham Hotspur are making it hard for his client to move on because of the price tag on his head.
Spurs manager Mauricio Pochettino is believed to be open to Wimmer leaving, but the club reportedly want £20m for the 24-year-old, who made just four Premier League starts last season.
"They 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. We have to wait and see what is happening on the English market."
Wimmer joined the club from FC Koln in 2015.
