"If I bring my best game, I can scare him early on and it will be a terrific contest.
"The form he has shown this season and in the first round, he is definitely the favourite for our match and the whole tournament now."
Trump admitted that good fortune helped him in his match against Welshman Dale.
"Up until then it was all going his way, but I think that [seventh] frame was the turning point. He started to miss a few after that and I capitalised on that," he said.
"I didn't play too badly but it was scrappy in some of the frames. I made a few big breaks and felt good in the balls but just hit the bad shot now and again. I need to cut the silly mistakes out."
After reaching the world final in Sheffield last season, where he was
defeated 18-15 by John Higgins
, the attention is on Trump to perform well at tournaments and entertain the crowd.
"There is definitely more of the spotlight on me now and everyone is watching, expecting me to play well all the time now and wanting me to pot all the long balls," he said.
"I enjoy having the pressure on me. It's nice going in to a match being expected to win and hopefully I can achieve that against Ronnie."
