The first player to message Mauricio Pochettino after Tottenham's disastrous end to the 2015-16 season was Harry Kane.
Within 24 hours of Tottenham's humiliating 5-1 defeat at Newcastle that saw them concede second place in the Premier League table to Arsenal, Kane sent his manager a text to thank him for what he had done for him that season.
Of all Tottenham's players, Kane perhaps owes the South American the most and few, if any, are closer to him.
In his diary of last season, Pochettino tells of how he arrived at the club to find Kane had all the habits and mental characteristics of a player in his 30s.
