Blues favourite Sam Warburton put in a man of the match performance in Murrayfield that saw Wales beat Scotland and England also beat Italy on the weekend. Rob Howley's men can still claim the Championship title if they beat England by eight points and in the process stop the Red Rose side from claiming the Grand Slam title in Cardiff.
Cardiff City Centre is sure to be buzzing on Saturday morning with tens of thousands of supporters descending on the Welsh capital. Following the final whistle, local band, and Cardiff Arms Park favourites 4th Street Traffic will be performing in the Arms Park courtyard - hopefully celebrating a Welsh win.
Speaking ahead of match University of Glamorgan student Owain Gruffudd said,
"I'll be coming down to the Arms Park on Saturday with a few mates to watch the game and willing the Welsh team on to 'Stop the Slam.'
"Unfortunately I don't have a ticket for the game but the next best thing is to watch it in the Arms Park Clubhouse.
"There's always a great atmosphere down there and normally a party afterwards with 4th Street Traffic playing.
"Hopefully we will be celebrating a Welsh win and see us retain our Championship title."
