The Englishman eventually came through a tough second round match with German Simon Rösner, winning 11-4, 6-11, 9-11, 11-6, 11-8 at Drexel University.

He went 9-0 up in the fourth game before eventually seeing it out and forcing the decider.

"I was probably down and out there at 2-1 but thanks to my team in the corner - without them I might have lost the belief," said Matthew, the fourth seed.

"I got a good start in the fourth and just told myself to stay patient. 

"I feel like I haven’t won a match like that in a little while so it was important for me to win it any way possible. 

"I kept telling myself I had the experience of seeing out these matches and ultimately that proved to be the case.

"I came into this match thinking Simon was the favourite and that I have nothing left to prove and it’s the same thing in the quarters. 

"I’ve played Ali twice and he’s beaten me twice, so I’m just going to enjoy it."

France's reigning world champion and second seed Gregory Gaultier joined Matthew in the last eight of the World Series tournament by defeating New Zealand's Paul Coll 11-7, 11-7, 11-6.

There were also wins for two Egyptians, with Ali Farag beating his compatriot Fares Dessouky 11-7, 13-11, 8-3 - after his opponent retired in the third.

Karim Abel Gawad, the fifth seed, needed to go the distance to beat Hong Kong's Max Lee, 4-11, 11-8, 9-11, 12-10, 11-6.

In the women's tournament, England's defending champion and second seed Laura Massaro eased through against Indian number one Joshna Chinappa, 11-5, 11-5, 11-6.

The home crowd had something to cheer as Amanda Sobhy ousted Donna Urquhart of Australia, with the seventh seed winning 11-7, 5-11, 11-5, 11-5.

France's Camille Serme beat Annie Au of Hong Kong, 11-5, 11-6, 11-6, with Egypt's fourth seed Nouran Gohar also progressing, 11-7, 11-8, 18-16 against England's Emily Whitlock.
