at www.soccernet.com under the US page there is a link to a Chris Rolfe chat which will happen tomorrow, and they are accepting questions today. Since I am a huge fan of his play, I am here to promote this chat. You should all submit a question (I prefer USMNT-centric questions...but feel free to ask about the Fire too), and check out his responses. I asked about whether Arena has told him what he thinks his strengths are weaknesses are, and how to translate his play to the international level from MLS.
I'm not a subscriber either but I managed the catch it while it was happening before they locked it out to only subscribers. The cool thing is he answered your question. I don't remember exactly what he said but it was something along the lines that Arena told him to continue to get more professional/international experience as well as learning to use his body better against bigger stronger oppenents.
That sucks that we can access it, hopefully in a few days. I didn't remember to catch it, hopefully it wasn't softball question like the one landycakes had to do.
