Germany's win against Portugal has left Rafa and his Dutch team-mates with it all to do to progress to the knockout stages.
Indeed, defeat against Germany and a Denmark win against Portugal will mean it's all over with a match remaining for the men in orange.
"We really have to go for it now," added Rafa, who prepares for a 7.45pm kick-off in Kharkiv, Ukraine.
"If we had won (against Denmark) then we knew a draw against Germany would mean we were already doing well, but now we just have to win twice. We have to wait and see what happens."
"We have to win twice to progress - we have to, that's a clear mission," said the forward after Holland's surprise 1-0 defeat against Denmark in their Group C opener on Saturday.
