Just one goal in 180 minutes of football produced some unpredictable responses. League leaders Sun Hei were held to a goalless draw by lowly Fukien, leading to coach Koo Luam Khen calling for his own head to roll, while Rangers, rapidly becoming Hong Kong's most dysfunctional club, were left desperately unhappy by a 1-0 victory over Sunray that sent them soaring into second place in the table. 'I think they should sack the coach for not winning,' Koo said light-heartedly, when asked if Sun Hei should take similarly drastic action to their rivals Happy Valley with their as-yet unfulfilled threats to fire half of their players. Indeed Koo, as ferocious a critic of his team as you could hope to meet when they win, refused to even contemplate the fact that the defending champions have now dropped five points in two games against teams from the bottom three. 'There's still a long way to go. Don't be silly,' he chided. 'They [Fukien] did very well defensively. They threw their bodies behind the ball. It's difficult to break down when there are eight or nine at the back.' Koo had not seemed as content when his Brazilian defender Cristiano Cordeiro was sent off for a second yellow card with 20 minutes to play, and was lucky not to follow him for entering the field of play to protest. However, the mood in the Sun Hei camp compared favourably to that of Rangers, who beat Sunray thanks to an acrobatic left-footed volley from Cameroonian central defender Armel Tchakounte in the 75th minute. 'Even though we won I'm not happy,' said team manager Philip Lee Fai-lap. 'We need to work harder in training. We need to improve. We still have players like Yip Chi-ho who cannot play for 90 minutes. How can you not play for 90 minutes when you're 19 years old?' It was an undistinguished Rangers performance, with several of the team members making clear their displeasure with one another, while Brazilian striker Eder Ferreira twice missed the target completely from close range. 'It was a very difficult game. It was difficult for everyone. We haven't played a game as hard as that all season,' said Tchakounte. 'Fortunately, by the grace of God, I scored; with my left foot; which is rare.' While Rangers continue to be football's version of The Simpsons, Sun Hei uncharacteristically can't find the net. Top of the table they might be, but they have scored only six goals and the last of those was 184 minutes ago. 'They attacked us too slowly,' said Fukien coach Alex Chu Chi-kwong. 'It was easy for our team to get back. They played too many square passes as well.' However, Koo's philosophical approach to a rough patch seems to echo around his squad. 'It's not as easy for us this year, the teams are closer together. And as a striker you can have problems scoring, but when you break the chains it soon comes back,' said Nigerian forward Cornelius Udebuluzor.
