Salem achieved one of the biggest wins of his career against World No.9 Miguel Rodriguez in round three, but he lacked the dynamism that saw him upset the Colombian and Coll picked him off to set up a semi-final meeting with either 2017 World Champion Mohamed ElShorbagy or his younger brother and 2017 runner-up – Marwan.
"I'm very happy to be in the semi-finals of a World Champs, it was something that was a minimum goal going into the tournament," said Coll from Greymouth on the West Coast.
"I've got to put that behind me now, even though I'm very happy to be in the semi-finals, I don't want to stop there. I've just got to regroup after this, enjoy the moment while it lasts and watch the match later. I just wanted to dominate today. Yesterday I felt like I got a bit dominated and my natural game was taken away from me, so I wanted to step up today and really take the game to Zahed.
"He had a tough match yesterday as well, so I knew it was going to be about who could dominate today. I feel like I did that for most of the game which got me over the line.
"They're [the ElShorbagy brothers] both quality players, I just hope it takes about three hours and then tomorrow I'll play whoever wins," said the 27-year-old Coll.
The semifinal match is set for around 4am NZT tomorrow (Friday).
