Is brighton actually depend with luck? i don't think so. Brighton knows what's gonna be the weakness from potter. I think that brighton has been using all of its performance against chelsea. Chelsea has been making so many mistakes. I think we can't deny that if the fact that chelsea was making it possible started from some of its players who have been making serious mistake. Chelsea needs lots of evaluation to the its players. Im sure that if chelsea will be trying to take an opportunity to make it happen.
