Karl Robinson has called for his side to up their performance level for Tuesday’s trip to Fleetwood Town.
He said: “There’s two ways of looking at it - it’s not great in that we’ve not played well but on a positive note, we don’t know how important that point might be for us at the end of the season.
“Vale have seen this as a very good point. The grass hasn’t been cut in seven days, it was very dry, and it bobbled up to the knee. But we haven’t been able to play as cute as we wanted to, but we have to make sure it doesn’t happen again.
“We worked hard, but every pass and control came away from us. Sometimes we have them. But we haven’t been beaten.
“Sometimes you have to wash your hands of games. A point is probably the right result, we didn’t do enough to win today.”
He added: “It’s another clean sheet and we’re undefeated in six games. Overall, if anyone was to offer us four wins and two draws in the last six, we’d take it.
“The players need to realise they’ve not played well, but we need to make sure we get it right before Tuesday.”
The stalemate and Preston’s 1-1 draw with Bristol City means the gap remains at five points with five fixtures to play and the 34-year-old isn’t giving up hope.
“There’s still 15 points to play for,” he said. “If we can get above 85 points, that historically has been enough. We set a target. If Preston surpass that you’ll have to shake their hands. But we’ll push them all the way.
“I want to finish third if we can’t finish second.”
