"Paulo is a good manager but he has a lot to learn as well. He should keep his mouth shut if he doesn't understand the circumstances.

Former Palace striker Shefki Kuqi scored the only goal 14 minutes into his first start for the Swans. Kuqi took full advantage of a defensive mistake to slide home past Palace goalkeeper Julian Speroni but he refused to celebrate his strike.
Despite the Finn's impact last night, Warnock warned Sousa that Kuqi's performances could tail off. He said: "He always starts well at a club, so I'm sure he'll do well for a few months. We'll have to see."
