Arsenal's new Puma kit has reportedly been put on sale in stores in China before the official release date.

The Gunners team will wear the new strip during the 2014-15 campaign after Puma secured a £150m deal with the North London outfit following the end of their partnership with Nike.

Despite the shirt yet to be officially unveiled by Arsenal, a supporter recently tweeted a photo of the new strip, which is believed to have been on the racks in Puma's Macau store.

According to the Daily Mail, Arsenal officials have stated that any merchandise on sale before July 10 will not be deemed official by the club.

A photograph of Olivier Giroud with former Arsenal stars Thierry Henry and Bacary Sagna wearing the new Puma attire is said to have been leaked earlier this year via athlete Linford Christie's Twitter page.
