"Tonight is arguably the biggest home game the Swans have ever played in Europe - even bigger than the Paris St Germain or Panathinaikos matches back in the 80s and early 90s when we were in the lower leagues. Chance for underperformers Bony, Amat and Shelvey to state their case for Premier League starting places. I think they are all coming good at once. Leon Britton is just a recent British football phenomenon and deserves to take to the pitch in such a proud night for this small but well respected Welsh club. They deserve a chance to play the biggest clubs in Europe. This is what the club has fought through the dark years if the last 20 years to see happen," says Dai Howells of Gower.
