The former Spurs U21s coach and technical director replaced Andre Villas-Boas as manager of the north London club in December with some questioning the appointment of the inexperienced tactician.
But Luongo, who was captain of Tottenham's U21s under Sherwood, feels the 44-year old is the perfect man to lead the club forward after learning part of his trade from Harry Redknapp.
"In fairness, he's a brilliant boss to have. Under him with the under-21's we won our league and I had a great relationship with him," he told SBS.
"When I wanted a chance to play regularly he even helped me out with my move to Swindon and I think he's just what Spurs need to push on again.
"People always talk about what a great manager Harry is at motivating players and while that's definitely the case, in my experience, Tim is probably even better.
"He's really your typical 'geezer' and is somebody everybody can relate to."
