CFA 'concerned' over Aubameyang reports

SHANGHAI - The Chinese Football Association (CFA) warned on Tuesday that it is watching closely and will punish teams that flout its transfer rules, following reports two clubs are battling to sign striker Pierre-Emerick Aubameyang.

Chinese Super League (CSL) champion Guangzhou Evergrande is reportedly prepared to pay at least $84 million for the Borussia Dortmund star, trumping an offer by rival Beijing Guo'an.

It is believed Evergrande, coached by Italian World Cup winner Fabio Cannavro, has agreed a deal to acquire Gabon international Aubameyang when the Bundesliga season wraps up in May.
