Tonight, Inter will have to do their duty against PSV at the Meazza. Obviously, it all depends on Tottenham because if the English club wins in Barcelona, the result in Italy would not matter.
Inter, in the last 11 participations in the Champions League, have only failed to make last 16 once and that was in the 2003-04 season when after winning the first two games, including the 0-3 against Arsenal in London, the team finished third due to the direct clash results with Lokomotiv Moscow. This scenario is very similar with what is going on between Inter and Tottenham.
We will know for sure if history repeats itself in about 6 hours.
