Does the relationship between teams and matches have a many-to-many cardinality ratio? Diagram
I created the following diagram:

Considerations
So I will create two tables, one called Match and the other one called Teams. In Match there will be data about two teams, Away and Home.
Let us take into account that each team can have take part in many matches, and a match can have exactly two teams.
Questions

Is this considered a many-to-many (M:N) relationship?
Is there anything I can do to change it?
Is this your full design or just a trivial example?

Suppose you want to store information about a team in a match


who was captain of the team during the match
any kind of stats of the team during the match
and so ..


If this would be the case, I would opt for a many-to-many design.
