Last Saturday’s Up for the Match featured two of Galway and Waterford’s biggest hurling fans on the show. And now Des [Cahill] and Gráinne Seoige] are looking to find their Dubs or Mayo for Sam equivalent!

To enter, send in your videos outlining why you believe you are either Dublin or Mayo’s biggest fan. If possible, make sure to film in landscape rather than portrait. The more imaginative or creative you can be with your videos the better as we will be making our decision based on the content that really stands out.

A selection of the best videos will be broadcast on the show on Saturday 16 September.

So if you think you have what it takes to be your county’s biggest fan send your video to our dedicated email address: biggestfan@rte.ie

Please make sure to put your county name in the subject heading, and include a daytime telephone number.

The closing date for the receipt of entries is Tuesday September 12
