"Of course there's irritation within the team, we are without a win in five straight matches in the Bundesliga... there is irritation".
England defender Danny Rose is in the frame to start, but Pochettino refused to comment on rumours Rose was "fuming" for being left out of Saturday's derby.
"Before I didn't put him in the team against Stuttgart, I told him already this would be a match he wouldn't play, but after, on Saturday, he trained with us, with the team, and that's why I can tell you now he'll play tomorrow".
"Everybody thinks we can't win tomorrow because it's such a bad phase", Bosz said.
He added: "It's always important to compete and to be focused on the next game and when you lose, it's important to play as soon as possible to change that feeling".
"We are positive, very positive, because the performance was good, the effort was good", he said.
"The objective was to qualify and we've achieved that, and now it's important to finish first if we can".
Pochettino said it shows how far Spurs have come in recent seasons that they were heavily criticised after losing to Arsenal. Then when I get the perception I'm going to decide.
The 45-year-old told reporters: "I hope not too many players rest tomorrow".
"I am happy though that people criticise us, this means they expect more of us, they see us on that level".
