Zambrotta said: “It’s not necessary to ring the alarm bells. If you play against great teams, it is possible you’ll lose. It is something that can happen.
“The surprising thing is to do so against teams that aren’t so good. I think that we did not play badly and these two teams still must come here.
“It is clear that it hurts a little. To never lose is impossible, but the important thing is that we have the possibility of turning a new page on Saturday in the Liga and also playing Chelsea again.”
