Harry Redknapp was in touch with staff at Tottenham last week.
Redknapp was shown the door by Spurs a fortnight ago.
Former manager Redknapp has spent the week ringing round former employees at Spurs to thank them for their help during his time at the club and joked with the club dentist that, now he is out of work, he will have time to fix his teeth, says the Mail on Sunday.
