Enthusiastic Manchester United fans stormed the field and briefly interrupted a training session held by the English soccer powerhouse in the southern city of Guangzhou on Thursday.
After star players like Ryan Giggs and Wayne Rooney emerged from the locker room to loud cheers, a sea of screaming Chinese fans ran onto the pitch at a Guangzhou stadium, with some taking pictures, Hong Kong television footage showed.
The players were sent back to the locker room and waited until the crowd dispersed before returning, Vicky Ho, a spokeswoman for United's Asian tour, said.
Ho said none of the players were injured, although they were overwhelmed by the passion of their Guangzhou fans.
The chaos was initiated by one or two fans who rushed to the pitch once they saw the team arriving, she said.
Thursday's practice session came ahead of United's friendly match Friday against local team Guangzhou Pharmaceutical — the last stop of the club's Asian tour.
United previously beat FC Seoul and Shenzhen Xiangxue Eisiti in Macau earlier this tour.
