Player availability list

I am trying to record players availability for team matches throughout a
season. For example I have say a possible total of 50 players and there are
say 40 matches throughout the season. So far about 30 players have advised me
for which of the 40 matches they are available. I wish to record this
availability in Access and then to be able to advise the match manager of the
various games which players are available for the match for which he is
responsible.
I have so far created one table of matches - recording date of fixture,
opposition, venue, match manager and a second table of players. My problem is
how to record which matches the player is available for and then to be able
to extract list of players available for a particular match. Any
help/suggestions would be much appreciated.
