Redknapp also criticised his own club for organising a pre-season schedule that he feels could be detrimental to their chances of qualifying for the Champions League group stages.
Tottenham played three games in eight days on a tour of the United States before returning to take on Villarreal at White Hart Lane on Thursday - a game they lost 4-1.
A trip to Portugal to play Benfica and a home game against Fiorentina follow.
"It's been busy schlepping around the place," said Redknapp. "We've just come back from a gruelling trip around America.
"It's crazy. And we pile more games in. The last thing we need is to be playing games.
"We need to train. I need to get the players on the training pitch because all we do is play and recover. We should be working in training.
"Too many games have been scheduled. I don't know whose fault that is. We play too many games.
"We play Fiorentina on the Saturday [7 August], which is a nuisance, then they go off and play for their countries," he added.
"They're going to have an international week before the first week of the season, before we play Manchester City and then a European qualifier.
"I won't see them from Saturday night until Friday before we play Man City [on 14 August], not once.
"Why? What's the point of it? A meaningless friendly. The week before the season, when we should be training, working, getting organised for the first game, they won't be here.
"How can that be a way to prepare for the start of the season? Then you've got your fingers crossed that not too many come back injured."
