England coach Sven-Goran Eriksson feels the Football Association's television deal is one of the reasons why he cannot experiment with team selection.
He said: "I'd like to experiment but it would be difficult. I'd be criticised from inside and outside the game.
"Who would criticise me? The media. Also I think it's down to TV contracts and things like that, such as money."
It is believed that the FA's TV deal states that England must always select their strongest available side.
Eriksson added that the friendly the England team are scheduled to play every November - such as the recent match in Spain - would be perfect for trying new players.
"I think friendly games in August and February are very important as they
come before qualifying games in September and March," added the England coach.
"It's more difficult to see the importance of the November game though.
"I'm sure a young team in
November would do very well. I would be happy taking no players from Champions League or Uefa Cup sides."
Players such as Shaun Wright-Phillips and Stuart Downing may be a given a chance to stake a claim for a regular place.
Eriksson also explained that he would need more time to prepare his squad immediately prior to the 2006 World Cup - if England qualify for the tournament.
"I hope we can have one week more preparation next season before we go to the
World Cup," he said.
"Fifa president Sepp Blatter has spoken about that, so hopefully he
is strong enough to bring it in.
"We can't have that as well as the winter break but, if we can have one extra
week's rest, then that would be very good."
