Spurs' number two believes the former Manchester United striker and Blackburn defender will boost title hopes with their knowledge of the pressures of big games
Former Manchester United striker Saha won the title in 2007 and 2008 with the Red Devils whilst Nelsen played in the 2010 World Cup for New Zealand.
Bond told the London Evening Standard: "That experience, that know-how, of having been there before [they are] the right type of characters, in the dressing room, on the training ground, and will be really really important for us.
"They've come in to be part of our team and part of our squad and the type of people that they are I think they can make an important difference to us."
Spurs have received a blow ahead of their crucial clash with Liverpool on Monday night as both Aaron Lennon and Jermain Defoe are rated as "extremely doubtful" with hamstring injuries.
And Bond believes the availability of key players will have a big say in the title race, claiming whoever can keep their best players fit will win the league.
He added: "I think players being available or not being available can play a big part in the run-in.
"At the top of the table or the bottom of the table you need your best players. That may end up being an important part of who wins the title and who goes into the Champions League."
