Great Britain indeed! Not just gold and a title retained but James Guy, Tom Dean, Matt Richards and Duncan Scott are the first precise-same-four relay quartet, in the 4x 200m freestyle and any other relay for men or women in the Olympic pool back to 1896 to keep a crown on their heads.

In 6mins 59.43, Britain's's very own awesome foursome became the first quartet made up of precisely the same four swimmers to retain the crown in any relay in the whole of Olympic history back to 1896. 

It had never happened before in the pool. It has now. A row of 1s appears next to each of their names on the result sheet: they gave no quarter, yielded not a drop to rivals as each member of the brotherhood of British swimming poured their hearts and souls into the tank at the Paris La Defense Arena.
