Leinster coach Michael Cheika admits he is happy his Leinster side still have their Heineken Cup destiny in their own hands, despite Saturday's defeat to London Wasps.
Cheika's men fell to a 19-12 loss to the 2007 European champions but the bonus-point they picked up in defeat means a five-point win over Edinburgh next Sunday will secure a quarter-final place regardless of Wasps' result at Castres.
"I am disappointed we lost the game but we are still in charge of our own destiny," said the Australian after watching his side fall to their second defeat in this year's group stages.
"There were a lot of different permutations during the game, but it was a really torrid encounter, to say the least.
"If we want to be sure of ourselves we need a bonus point next week."
Leinster found themselves trailing by 10 points inside the opening quarter of an hour at Twickenham but the Irish side fought back to ensure they remain top of the group with just one round left to play.
"We got hit early but we stayed on our feet and we got back into it," said Cheika. "We stayed in there, but we couldn't get any flow going, but credit to Wasps who played very well.
"We missed opportunities in the second half which probably cost us. We missed a goal which would have made it 16-15 and Rob Kearney's break, you have to take those opportunities.
"Conversely down the other end we made a game saving play when Josh Lewey made a break."
