Edinburgh conceded three tries in 16 first-half minutes as they went down to a 31-10 Magners League defeat in Swansea yesterday.

Moffat's side could not build on winger Tim Visser's try in first-half injury-time as they failed to score in the second period despite Ospreys losing Mike Philips to the sin bin.

Ospreys went on to secure a bonus point in their first Magners League win at the Liberty Stadium this season and Moffat has challenged his players to bounce back against Stade Francais in Paris.

"I felt we looked a yard off the pace," Moffat said. "We are disappointed, but we will move on and focus on the Heineken Cup.

"I felt we gifted them three tries and, against a quality side like the Ospreys, you cannot afford to do that. Defensively I felt we looked naive and made too many mistakes.

"We were playing catch-up and didn't finish off the chances we created.

"We were also slow to the breakdown and our play needs to be quicker, but we will move on and go to Stade determined to put in a better performance."
