Tunisia coach Roger Lemerre said one error cost his side a shock victory over Spain.
Lemerre said after the 3-1 defeat: "I am very disappointed because we had good tactics, but it all crumbled because of a single mistake."
Lemerre was referring to goalkeeper Ali Boumnijel, who gifted Raul an equaliser in the 71st minute. Spain went on to add two more before the end.
"All is not lost but we didn't win anything here either," Lemerre added.
The Frenchman's side face Ukraine in their final group game on Friday, when nothing more than a win will do if they are to have a chance of progressing further.
"The Ukraine game will be decisive and we will have to do a better job to make it to the last 16," Lemerre admitted.
"The route will be difficult, but we still have hope."
