With the North-East outfit three points adrift of safety with a game in hand over their relegation rivals, the Uruguayan coach says that a miraculous escape from the drop zone is very much on the cards.
Speaking to reporters ahead of Sunday's six-pointer with Cardiff City at the Stadium of Light, he said: "It's been a good week, yes, it's true.
"[The players] are human beings, normal people who were very down because of the situation, and then in four days, everything changed.
"Now the idea is, with all respect, we have done something very special, but let's say half of the miracle. The other half, we still need to make."
Sunday's clash is scheduled to kick off at 12pm.
