Tottenham Hotspur have reportedly sent scouts to gather more information about Ajax right-back Ricardo van Rhijn.
The 23-year-old has earned an impressive reputation in Amsterdam, and has been repeatedly linked with a move away from the club in recent seasons.
According to The Mirror, representatives from the club were present to watch Van Rhijn in his side's 3-1 loss to Paris Saint-Germain in the Champions League on Tuesday evening.
Van Rhijn is believed to be valued at close to £5m by Ajax, but reports suggest that both Napoli and Villarreal are interested in the Netherlands international and could compete with Mauricio Pochettino's side for the defender's signature.
Kyle Walker has emerged as Tottenham's first-choice right-back in recent seasons, but he has not played since March due to an abdominal injury.
