I've only seen 3 or 4 WeeNix games but thought Rufer was actually quite good. Often in space and picking good passes almost all of the time. Some very nice switches wide to Rogerson especially.
Certainly doesn't standout as much as Singh but I'd be giving him a contract. Also been reasonably impressed with his A-League performances this year. For me he's shown enough to have earned some more investment in his future.
