PETALING JAYA: Chen Tang Jie-Toh Ee Wei may be the reigning world champions but facing compatriots Goh Soon Huat-Shevon Lai Jemie in the Denmark Open mixed doubles quarter-finals promises to be a tricky affair.

Past encounters have shown just how evenly matched the two pairs are, with Tang Jie-Ee Wei winning four of their seven meetings, including their most recent clash in the World Tour Finals semi-finals in Hangzhou last December.
