BBC Sport's Ask Me Anything team looks at why Crystal Palace are using triangle-shaped corner flags this season.
Crystal Palace are using triangular corner flags at Selhurst Park this season as part of a tradition for FA Cup winners.
The custom dictates that the defending champions have the right to use triangle-shaped corner flags instead of the typical square versions.
It is rumoured to have started after Cardiff City won their first and only FA Cup in 1927, with other clubs following suit.
Recent winners Manchester United, Manchester City and Liverpool did not participate in the trend, but Leicester City did during the 2021-22 season.
The International Football Association Board (Ifab), the body responsible for determining the laws of the game, do not regulate the shape of the corner flag.
On making the decision to use triangular corner flags, Palace said: "After that unforgettable day at Wembley on 17 May 2025, we finally joined the winners' circle.
"The triangle flags are a simple but powerful reminder of that historic moment. From the stands it might just look like a flag – but for us, it is a symbol of making history."
