If Darren Anderton and Christian Ziege, boith 50-50, fail to make it the boss will be without nine injured players on the injured list for Saturday's first home Premiership fixture against Aston Villa.
Asked for his aims for the campaign, Glenn responded: "I can't judge where our main ambitions are when we have seven or eight injuries in the squad.
"If we can get to the stage where I can get a strong, bolstered squad then I think there is quality here that hasn't yet been seen, untapped quality.
"We saw it in a lot of moments last season. We got to a final and 20 minutes before the end of the final match of the season we were seventh, but we lost 2-1 and ended up ninth. Now seventh is somewhere the club hasn't been for years.
"I want progression but I can only really set those objectives with a better scene on the injury front.
"I want to get to the stage where I can rest players and pick my side for tactical reasons.
"A good sign for me was having Les Ferdinand as substitiute at Everton last week and he went on and influenced the game.
"That didn't happen many times last season and when you look at the top teams, that is where you judge the squad, on the bench. They can have such an influence in the last 20 minutes when games can be won or lost.
"Last season I had seven or eight players injured every week and if that changes I think we can have a positive season."
Glenn Hoddle says it's so difficult to nail down the club's ambitions with so many injuries.
