Sherwood, 44, wants to stake his claim to replace Andre Villas-Boas further when his side travel to Southampton on Sunday and made the announcement as speculation rises that Spurs want to approach Swansea about their manager, Michael Laudrop.
Laudrup says he is flattered to be linked with Tottenham Hotspur, but has no intention of leaving his club mid-season.
The 49-year-old Dane Laudrup is among the bookmakers' favourites.
"When your name is linked with another club, I assume it is because someone thinks you are doing well," he said.
"Tottenham is a big club... but I would never leave a club in the middle of the season."
He added: "I have never done that as a player, or as a manager. So I wouldn't do it in the future."
"It's not for me, to be honest, I wouldn't want that," he said when asked if he would accept a number two role.
"I know all about the football club, I've played here - it is my club. I know what the supporters demand."
Technical co-ordinator Sherwood has coached Tottenham's youth sides since 2008 and hasforged links with Swindon Town who have loaned a number of Spurs youngsters this season.
Ironically, given Sunday's game another potential boss being linked with a move to White Hart lane is Southampton manager Mauricio Pochettino. But Pochettino insists he has not had any contact from Tottenham about the job and claims he is happy at St Mary's.
"As a manager what's really important is that the sporting aspect is under my control, in terms of signings," he said referencing the fact Spurs technical director Franco Baldini has a role in choosing signings. "Without my agreement no signings go through, and those two basic things are very important for any manager."
Meanwhile the Tottenham Hotspur Supporters' Trust has demanded talks with chairman Daniel Levy over the direction of the club following Villas-Boas's departure.
