Tottenham Hotspur are reportedly targeting Olympiakos starlet Panagiotis Retsos as they continue to run the rule over defensive reinforcements.
Greek news outlet SDNA has claimed that Spurs recently sent a scouting team to watch the 19-year-old in action for his current club as manager Mauricio Pochettino looks to make late waves in the transfer market.
Tottenham are the only Premier League club who are yet to add to their first-team squad this summer, and have £50m burning a hole in their pocket following the sale of Kyle Walker to Manchester City.
Retsos was in action for Olympiakos in their Champions League third round qualifying match against Partizan Belgrade on July 25 and August 2, and it is at that latter game that Spurs' scouts checked to see whether the centre-back would be a worthwhile addition to the north London side.
