Can you name the only player to have been substituted in an international game, and was replaced by his brother? The game was held in Wembley...
Yes well done, it was David O' Leary, replaced by his brother who played with Shamrock Rovers at the time...
On a similar note, the only father to be replaced by his son at Anfield? It was a friendly. For charity.
I was going to say the Dalgleishs, Kenny and Paul, but I actually think Paul was on the pitch the same time as Kenny.... J.
