Real Madrid coach Jose Mourinho was shocked by the thrashing suffered by former club Inter Milan last night.
Inter were thumped 5-2 at home by Schalke.
"You never know in football. If we lose the Champions League then we still have the Scudetto and Coppa Italia to challenge for," said Mourinho, who won the Treble with Inter last season.
"I am very disappointed, as are all the Inter fans, but this is football and you never know what can happen.
"It feels like mission impossible in Gelsenkirchen, but you never know. It's not possible to always win."
