The Zambian striker was on target on Monday night in the 2-1 away loss to Qingdao Jonoon.
Chamanga’s maiden goal came after 70 minutes but by then Jonoon had already scored twice through penalty conversions by Liu Jian and Zhau Zheng and cruised to a comfortable victory.
Since making his debut on May 17 against Shaanxi Zhongxin in a game that ended 1-1, Chamanga has found no joy in front of goal as Haichang have been dismal as a team.
Haichang – China’s most successful club with eight league titles to their name - are in unfamiliar surroundings languishing in 13th position in the 16-team league with just 16 points from the 16 games that they have played. They trail leaders Shandong Luneng by 19 points with 14 games remaining.
“I have realised that football is much more physical and faster here,” Chamanga told KickOff.com a month after his arrival in China, where he said he has signed a one-year contract after being bought out of contract at Swallows.
The Chinese Super League has only resumed on August 30 after a lengthy seven week break to make way for the 2008 Beijing Olympics.
With Chamanga’s club chasing shadows, Serbian coach Ratko Dostanic has been fired after achieving just one win in eight games and has since been replaced by fellow countryman Milorad Kosanovic who makes a return to the club.
Chamanga is well out of the race for the top scorer award in China as Nigerian-born Poland striker Emmanuel Olisadebe of Henan Siwu leads the race with nine goals.
