The Italians trail Andre Villas-Boas’ side 3-0 from the first leg at White Hart Lane, but the Nerazzurri trainer feels that an exit at the hands of the Premier League outfit will not mean he will be sacked.
“My future will be decided by the results at the end of the campaign, not by one game,” he told reporters.
“I've always had the president’s backing, but he is in charge and can make whatever decisions he wants. I think that my work will be judged at the end of the season and not now.
"I never give up, I’m focused and giving everything that I have.”
Inter have lost their last two games and have just one win in four, but the 37-year-old insists he is concentrating solely on the clash with Spurs.
“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 added.
“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.”
