Van Dijk told BBC MOTD: "It feels like a loss, it is our fault again. We had so many chances and we should finish the game off. Unfortunately the individual mistake that happened with the equaliser and we had so much time to put it right, but we were in a rush. Still after being 2-1 down we created so much."
He added: "We should have been 2-0 up at least, but in football unfortunately if these things don't happen you give them the feeling they could come back and it happened."
Asked about whether Quansah will be affected by his error, he replied: "He shouldn't. Mistakes happen in football everyone who has a career in football makes mistakes you can only learn from it."
