The Swansea City keeper was part of the side that beat Norwich on Saturday at the Liberty and heads off to Barnsley this afternoon knowing that – in all likelihood – nothing less than four wins will do.
De Vries told the Evening Post "All we can do is win our games. It's as simple as that and hopefully someone will slip up.
"We've got to keep going and I think now everybody is really fresh and looking forward to the challenge ahead. We'll look forward to our next game and keep the dream alive.
"To reach the play offs all we've got to do is stick together asa team and keep on fighting for it because it's still on."
De Vries was instrumental again in Saturday's win and added "They had a couple of players that were a real handful. THey're physically strong and lively up front. They can cause many teams problems so it was a good result for us.
"We looked really good in possession and I had a feeling we could have done better. But in the end it's a good three points."
De Vries hopes also to commit his future to the Swans very soon "We're discussing a two year deal and hopefully it will be sorted out soon.
"All I'm concentrating on is Swansea City. I've got to keep on focusing on my performance on the pitch."
