Steve Hitchen sent the Tottenham staff a heartfelt email on Wednesday explaining his decision to resign as the club's technical performance director, football.london understands.
The 45-year-old asked Spurs chairman Daniel Levy on Tuesday to release him from his contract after five years at the club - 10 years in total following a previous spell as a scout.
That request was granted and Hitchen has now begun a period of gardening leave, with both Everton and Newcastle United believed to be showing interest in bringing him in to head up their new projects.
