The source revealed that he was among a number of regular Premier League stars who almost ended up being recruited by Forest, who have gone from major promotion contenders to being in a relegation scrap prior to the appointment of Chris Hughton in October.
Southampton took the Spurs academy product to the south coast in a separate deal agreed in conjunction with former captain Pierre-Emile Hojbjerg moving to north London.
The 23-year-old signed for a fee believed to be around £12m on a five-year deal, keeping him at the club until 2025. Having featured in 10 games in an initial six-month deal last season, the young man evidently impressed enough to sanction the conversion of his loan into a permanent transfer.
The London native is valued at £13.5m by Transfermarkt and has been capped at a variety of youth levels.
While Forest fans may be raging at the club not taking their opportunities, Saints fans must surely delight in knowing that their star defender was a coveted talent elsewhere before pitching up at St Mary’s.
