The Oranje lost 2-1 in Paris.
"We came here to win, not to lose. Losing is always bad," said Van Dijk.
"We are a little unfortunate. Mistakes are just part of football. We have seen good football in the second half at times.
"The fact that you do not get results, of course, dominates. We are fed up with it, we are very sorry. I personally am for sure. Anyway, there are enough positive points with which we can continue."
