The 27-year-old Chinese, an Olympic bronze medallist and the top seed, won the event last year to add to his success in 2013 but faces stiff competition this time around.

His compatriot Lin Dan, a double Olympic champion who won the Badminton World Federation (BWF) German Open yesterday, is sure to be in contention along with Malaysia’s Lee Chong Wei.

The pair have lifted eight titles between them since 2004 but it has been suggested that this could be their last appearance at the All England.

A sixth men’s singles title for Lin would see him join only three other players to have achieved the landmark in the 106-year history of the Championships.

He will open against South Korean Lee Dong-keun with Lee facing Parupalli Kashyap of India.

Chen will square off against an as yet to be determined qualifier.

In the women’s singles, Carolina Marin’s victory last year raised the profile of European badminton with the top seed facing a big threat from China.

Li Xuerui and Wang Yihan will trouble the Spaniard, as will Indian Saina Nehwal, the number two seed who begins against Michelle Li of Canada.

Malin will play Korean Bae Yeon-ju in round one.

Chris and Gabby Adcock, who won the year-ending BWF Superseries title in Dubai, are seeded seventh in the mixed doubles and will be a main home hope for success.

The All England, the first BWF Superseries of the year, is packed with prestige as it was first held in 1899.

“There is so much history,” said BWF President Poul-Erik Hoyer.

“The best are gathered, they’re all in good shape and it’s the tournament everyone wants to win.”

As well as title glory, the event starts the final sprint towards Rio 2016 qualification with key ranking points on offer.
