Shane Williams says his Ospreys side must up their game if they are to beat Saracens in their Heineken Cup quarter-final.
Williams said his team played 'in patches' as they beat Bourgoin 28-21 at Stade Pierre Rajon to secure one of the best runners up spots and a place in the final eight against Pool 4 winners Saracens.
Williams was pleased to progress saying, "It is the first time I have won a game in France so I'm happy with that." But he was far from happy with the manner of victory, "We only played in patches and didn't take the our chances to put them away."
After trading penalties to make the score six-all after 20 minutes, the Ospreys superior firepower told and they finished the match outscoring their hosts by three tries to two.
"Fairplay to Bourgoin they came back at us very strongly after we scored," said Williams.
"They started to throw the ball about like a ball form the top of the league should do
"They proved to be a difficult side to beat, I'm just happy to still be in with a shot at lifting the Heineken Cup."
