The best way is to change home team ID and away team ID to entry fields that select the club. If you are using a plugin like Feed Me to bring in the matches, and you have all of the club IDs already entered in the club entries, you should be able to import matches and use the home and away IDs and match them to the appropriate Club in Feed Me.

Once that is done, you won't have to loop through all of the Clubs, just pull the one from each of the matches home and away fields like so:

{% for team in fixture.homeTeamId.limit(1).all() %}
    {% for logo in team.clubLogo.limit(1).all() %}
        &lt;img src="{{ logo.getUrl() }}" /&gt;
    {% endfor %}
{% endfor %}


If your API isn't brought in with Feed Me (or akin) and you can't change the home/away fields to entry selectable fields, you can select a team by matching its ID field to the given ID field like so:

{% set awayId = fixture.awayTeamId %}
{% set awayTeam = craft.entries.section('clubs').search('clubId:'~awayId).limit(1) %}
  {% for team in awayTeam %}
    ...
