Question : How do you query a many-to-many junction using LINQ?

I am trying to query a junction table using LINQ but I can't see the entities. Please see database diagram for further details.

I originally had this setup with the Match table that had to extra fields TeamAID and TeamBID, each with a foreign key relationship to the Team table primary key. To access the TeamA fields I could simply use m.Match.Team.Name, etc., or TeamB's fields by using m.Match.Team1.Name.

Then I decided to use a many-to-many relationship using a junction table, but now that I have a many-to-many relationship I can access the fields.

What am I am doing wrong?

          //OLD CODE
            IQueryable matches = from m in db.Matches
                                 where (m.Date >= date && m.Date <= date.AddHours(24)) &&
                                 m.Stage.Name == stageName &&
                                 m.MatchDay.Title == matchDayTitle
                                 orderby m.Date
                                 select new
                                 {

                                 orderby m.Date
                                 select new
                                 {
                                     MatchDay = m.MatchDay.Title,
                                     Time = string.Format("{0:t}", m.Date),

                                     TeamAName = m.MatchTeams.????,
