Van Gerwen will next face Chris Dobey and he stated that performance is why you should never write him off.
He gave King credit as well saying he is a top class player who pushed him to his limits and also admitted he is only going to get stronger now.
"I think it was a phenomenal game from both of us, but I proved why you should never write off MvG," said Van Gerwen.
"He pushed me through the roof, he never gave up and I think we saw Mervyn at his best tonight. He's a top class player with an incredible talent.
"Now I will have a good night's rest and I will be ready for tomorrow. I think the longer format will favour me in my game with Chris."
