The Socceroos boss insisted that his side deserve more than one point from their group campaign so far, having pushed France all the way during a 2-1 defeat in their previous match.
"I feel we should have won. It's like against France: I'm disappointed and proud, and feel we deserved more. I honestly think we've deserved four points from these two games. So I'm very disappointed," Van Marwijk told reporters during his post-match press conference.
"It is just the last piece of the puzzle we are missing. Now we must concentrate on Peru; the rest, in terms of whether we can qualify, we cannot influence."
