Didier Drogba insisted a new challenge and not money was the motivating factor for his move to Shanghai Shenhua. The former Chelsea striker was presented by Shanghai today after last month agreeing a two-and-a-half year contract reportedly worth £200,000 a week with the Chinese Super League outfit. The 34-year-old Côte d\'Ivoire international said at his unveiling that the desire for a \"big challenge\", and not financial reasons, was behind his decision to quit Europe for Asia. When quizzed on his salary, Drogba said: \"It\'s not really important, the most important thing is I come here to help Chinese football.\" He added: \"The money\'s not really what is the most important thing, because everybody knows that I give a lot of my money to my foundation, so really I didn\'t come here with the idea of making a lot of money. \"I know China is a great sports country, so for me it was also a big challenge because it would have been easy for me to stay in Europe and go to another team, another big team, but I want to achieve this challenge so that\'s why I decided to come here.\" Drogba played a key role in last season\'s Champions League success with Chelsea, while he also won three Premier League titles and four FA Cups during eight hugely successful seasons at Stamford Bridge.
