Inter Milan president Massimo Moratti knows they must pull off the impossible if they're to reach the Champions League semis.
Inter face Schalke needing to overturn a 5-2 deficit in Germany.
"We need to stay concentrated," the Inter chief said outside of his offices in Milan on Monday evening.
"We need to try to achieve something that seems impossible, even if the impossibility makes this tie fascinating.
"We'll take things a day at a time in the Champions League and in Serie A and then see what happens in both."
