Taking charge of the first team affairs in a caretaker capacity following the departure of Glenn Hoddle, David's first game back comes with the cup trip to Coventry City on Wednesday, a game he views as vital in terms of getting back into winning habits.
"We've just got to try to stabilise things as players will have all sorts of thoughts going through their heads," said David just before taking training along with Chris Hughton at Spurs Lodge.
"We've just got to be positive and get back on the winning trail, which breeds confidence. We'll pull through it, decisions have been made and the club has got to go on and be strong.
"We will all focus our minds on the immediate future. There is no future in the past - that is sad, but true.
"Every game is important. We want to win games and would like to have a Carling Cup run, we want to get up the league - we want to do all the things that the supporters want for us.
"It will take a big effort by everyone, everyone has to be true to themselves and I'm sure we can improve things."
David Pleat says undivided attention must be directed towards the immediate challenge of making progress in the Carling Cup.
