Ospreys winger Shane Williams:
"It was a great start, but it's a shame we couldn't capitalise on it.
"They were a strong team but the tries we conceded were quite poor considering the effort we put into the game.
"It always takes the stuffing out of you but we didn't deserve to win. But we could have done with a bonus point."
