サッカーチームって英語でなんて言うの？

1. The 'squad' is enough if you are talking about a certain team. Or you could say, for example, 'The England squad'.
2. Similarly, 'The selection' could refer to a specific team you are talking about.
3. Commentators often refer to, "The line up" or "The starting line up" when talking about the players scheduled to play in a team.

There is no specific term that is used when referring to the soccer team. We usually say "football team" or "soccer team".

In English, there isn't a very specific nickname for a soccer team. We usually have to mention more than a number in order to understand if we are referring to a soccer team.

Some of the words we could mention are words such as:
1) Soccer Team
2) Soccer Team Players

Sometimes we could also mention about a "Soccer Squad" but it is not very common.

We don't have any causal ways of saying soccer team but here in the UK we refer soccer to football.
Example - 'Tom play's for a good football team' .
