Cygan for one, definitely won't be missed. He never really had a good time in Arsenal. At times, he would be immense and almost winning every aerial header. At times, he would look so lost and so slow and made to look silly by strikers. I'm glad Arsenal offload him and still made some money. But i'm thankful for his contribution.
As for Reyes, i have no qualms about him leaving. He's one of the more hardworking players on the field, doing all sort of running and chasing down lost balls. His assist rate is the highest last season, so no complains about his contribution. I felt he had every potential to be a great Arsenal player but its a pity he couldn't adapt to life in London. An unsettled player will never perform at the highest level, fact of life.
Cole dissapoints me most. He was the wonderkid on the left side that was brought up by Wenger single handedly. He showed so much potential and even managed to dislodged the lightning quick Silvinho and the more experience Van Bronckhorst. When Chelsea made an approach, he gladly met them and was caught red handed and was subsequently made the sacrificial lamb for Arsenal to have a go against the mighty cash rich Chelsea. From that moment, it was all over for his career at Arsenal as you could see his performance isn't the same anymore. I hope he takes the SWP route and never perform as he used to at the old club. And when he retires, he can look back at his career and finds out his best playing time was with Arsenal.
