Jihai is still playing in China for Guizhou Renhe.
He told evertontv: "I think, for football in China, we are on the way up.
"First of all we have to make our league better and the quality stronger. Then we will have a chance to produce a quality player who could play in the English Premier League. Players like Yakubu can bring experience and can take the team he plays for up in stature. He can pass his quality to others and that's good for Chinese football."
