Tottenham did some very good transfer business in the summer but could the decision to offload Kyle Walker-Peters to Southampton eventually return to bite them?
Spurs decided to cash in on the young right-back, with the Saints only too happy to turn their loan deal from last season into a permanent transfer.
The deal cost the Saints £12 million and already looks like a stunning piece of business by Ralph Hasenhuttl.
Tottenham have gone with Serge Aurier and Matt Doherty as the two right-backs this season.
Aurier has started to perform a little better under Mourinho but the £14.7 million signing of Doherty hasn’t really worked out.
The ex-Wolves man has started just eight games in the Premier League and has largely been used as a backup to Aurier.
At 29 he is six years older than Walker-Peters and Southampton’s gain is proving to be Tottenham’s loss.
Some statistics from Who Scored prove how valuable the young Saints star has been this season.
He is sixth in the Premier League for most successful tackles, with 50 from his 18 appearances.
Walker-Peters has also made nine tackles this season, which also sees him sit seventh across the whole Premier League.
The £30,000-a-week youngster inevitably wanted to play regular first-team football but neither Tottenham right-back will be deemed a long-term option.
Walker-Peters would have got plenty of chances to play this season, with Spurs fighting for silverware on four fronts.
Hindsight is a wonderful thing but stepping up at St Mary’s is simply showcasing that Tottenham didn’t need to sign Doherty.
Walker-Peters left North London having made 24 first-team appearances but it could have been many more.
Tottenham’s business over the past 12 months has been largely good, especially when it comes to the players added.
Letting Walker-Peters leave could prove to be one decision they live to rue, however.
