"What I understand his comments to mean to the Los Angeles Times is that, where applicable, his team would utilize a greater number of international players through the currently established and allowable means of Senior Internationals (three spots), Transitional Internationals (two spots) and on the developmental roster (six spots)." "I would speculate that perhaps above and beyond that Vergara would look to have players who speak Spanish or boast a Latin American heritage on his team." Earlier, Los Angeles Galaxy vice president and general manager Doug Hamilton gave an indication of what the current MLS teams would make of any rule change, noting Vergara has to comply with the US top-flight's current rulings. "Well they have to," he stated. "There are competitive reasons rules are in place. "We are a single entity League and they need to play under the same rules that we do. It's really that simple for me, I don't see any way around that."
