The Swansea City goalkeeper said that he thought the effort had crossed the line for a goal which would have given the home side the victory that they wanted.
But Lee Mason ruled that there was no goal and the Swans earned a third consecutive draw in the league to maintain their 9th placed position in the league.
Speaking to the Western Mail, De Vries said “I have to be honest, I thought it had crossed the line
“I haven’t seen it back and I certainly didn’t know it for sure but my instinct at the time was that it did.
“It was a messy one because I think it touched Angel Rangel, touched me, went through the legs of Ashley Williams and I think it crossed.
“But I certainly didn’t know for sure because I was on the line before Ash got there and in a split second the ball was gone.
“Who knows, but we can have a bit of luck in that respect when you look at some of the goals that have gone against us – even the penalty that Cardiff had last week. We deserved this clean sheet.
“It’s part of the job of making saves and of course it’s nice to be back from quite a nasty injury,” he said. “It was only my third game back since it happened but I feel I’m getting more confidence with every game I play.
“The first one definitely came off Tatey with his first touch! It was a nasty one because those free-kicks are so hard to judge when they whip them in and all you can do is be ready to make a reaction save should anyone get a touch.
“Now I’m looking forward to getting rid of the mask on Tuesday – I don’t think it’s lucky because I’m not superstitious but I will keep it as a memento!”
