Welcome to the Q&A Forum

What if instead of creating a new page every time Team A has a match with Team B, you reused the same URL, updating the content to reflect the new match? (You could even build additional content by listing the results of previous matches on that page.) Not only would you then be avoiding the duplicate title tag issue, you'd also be building a long-term presence for that recurring matchup on a single URL.

Great advise here, Just to add Google Search Console seems to update it's index slower than the search index so it is possible to see old errors longer than they exists until it is re-indexed. Kind Regards Jimmy
