Shenzhen Jianlibao captain Li Weifeng is concerned that fatigue could interfere with their flight towards the top of the Chinese National Football League. Their home match against Beijing Hyundai this afternoon will be their fifth in 19 days in the packed post-Sars schedule and their third in the stifling heat of Guangdong province. Shenzhen have soared into the title reckoning with three wins and a draw but Li, the national captain, is worried that the cumulative effect of so many games is starting to show. 'Physically we are very tired. It's been very hot in Shenzhen, which makes it worse,' he said. 'It all depends on our mindset. It's difficult to say, but we have maybe a 60 per cent chance of winning.' Shenzhen's charge up the table has been helped by a significantly strengthened squad that has stayed free of injuries. This afternoon the depth of talent will be tested as striker Li Yi and Yugoslav midfielder Dejan Radenovic are both suspended as the two teams renew a long-standing rivalry. It's a rivalry that will change soon as the Beijing side will have four players - Yang Pu, Xu Yunlong, Tao Wei, and Shang Yi - training alongside 10 Shenzhen stars in the 'Dragons' team that will face Real Madrid in the capital next month. 'I think Beijing have very good players, but they'll be tired too,' said the Shenzhen skipper of their opponents who are just three points off the foot of the table. 'They have a very long trip. And of course Shenzhen is much hotter than Beijing. If it stays hot and humid we'll have a very big advantage.' It's not only Shenzhen who are struggling with the heat and the hectic schedule. Even for the northern-based teams, such as the seven-times C-League champions Dalian Shide, the height of summer is proving a demanding time. ' It's the same for all of us,' said Dalian coach Milorad Kosanovic. 'We can't change the climate of China. We have to be clever in how we prepare our teams. Summertime in China is very difficult for football, but it's also a good time because the pitches are in good condition.' Dalian, who started the weekend in second place, are at home to the Shandong Luneng Taishan side that Shenzhen defeated in Jinan on Wednesday night. 'This will be a big match - a very important match for both teams,' he declared. 'It's important for them because they lost on Wednesday and this may be their best chance to keep in touch with the top teams.' In today's other matches, Shanghai Shenhua should have few problems maintaining their lead as they face a Bayi side that is desperately out of form. Of the gaggle of clubs in mid-table Yunnan Hongta host Tianjin Kong Shi Fu, while the chameleon-like Liaoning Zhongshun play their first game in Fushun's Leifeng Stadium since quitting the capital; the team, formerly known as Beijing San Yuan and Liaoning Bird, face Qingdao Bright. In last night's match Shenyang drew 1-1 with Shanghai Zhongyuan. Hong Kong yesterday beat Guangzhou Xiangxue 1-0 in a friendly in Qingyuan, with Lee Kin-wo scoring the winner in the 62nd minute. It was Hong Kong's last match before they return to the SAR to complete their preparations for the friendly against Liverpool next Sunday.
