He will play Raymond van Barneveld in the last eight and told Sky Sports Main Event afterwards: "I will have to play better against Raymond than I did in this game, simple as that".
Cross took advantage of uncharacteristically poor finishing from the Dutchman.
"I'm really glad I was the victor". They got on Michael's back and that's why I won.
"I will come out (in the final) and want to win".
"It's the greatest feeling in the world hearing the fans chant my name and I'm going to miss it after this week". I never expected this rise, I really didn't.
"I never expected this, it's incredible, absolutely amazing".

Webster missed three doubles to draw level at 2-2 in the third set to open the door for Lewis, who returned to the oche to hit double eight and move 3-0 up.
The 27-year-old has well and truly leapt out of anonymity and will face Taylor in a final that will have Sky Sports' ratings counters rubbing their hands together. "Rankings don't mean anything until I'm number one".
Taylor will end his illustrious career with another final appearance after beating a wasteful Jamie Lewis.
"That's a positive thing for him but the negative thing is I'm through to the next round".
