Inter go into Sunday's Serie A match having won just three matches in their past 12 outings.
“I think that my work will be judged at the end of the season and not now,” said Stramaccioni, whose side remain fifth in the standings only six points behind second-placed Napoli.
“I’ve always had the president’s backing, but he is in charge and can make whatever decisions he wants.
“My future will be decided by the results at the end of the campaign, not by one game. I never give up, I’m focused and giving everything that I have.”
Stramaccioni is looking for a win against Spurs in the Europa League last-16 second leg at the San Siro, but knows overturning the 3-0 loss at White Hart Lane in the first leg is almost impossible.
“We have to just think about this game. The 3-0 will be hard to overturn, but we want to win. We’ll also need a little bit of luck,” he said.
“We’ll give it all we have got. Our squad is limited, but we want to honour the game.
“Tottenham have an awful lot of quality. We'll try to contain them and we'll see how well we manage that tomorrow.
“You need more energy in this competition than the Champions League. If I could go back in time, I would have made different team choices.”
