When you are taking with your friends about a sport, then you can ignore the "队" and your friends can understand what are you saying. So if not in this situation, don't miss it! Bruce 🐈🐈

Hi, Sara! In the context of a sporting event, yes, they do have the same meaning. Native speakers tend to keep the 队 when speaking though so that it's clear they're referring to a sporting event and not an actual conflict between two cities.

Also, it's not necessary to include spaces in Chinese the way we do in other European languages. 北京对广东，这样就可以, and through context, it's understood you're talking about a sporting event. The 队 character isn't really necessary, as others have said here (:
