Wasps coach Shaun Edwards:
"The improvement in Saracens is staggering, and they certainly are a force now.
"I knew they'd be tough as soon as I saw their team sheet. They've got some fantastic players and they've been the best team in the competition in the last month - which is why Mike Ford won the coach-of-the-month award.
"We'll certainly be looking at getting a bonus point at least against Leicester on Friday. We might have to go away in the semi-finals to win it."
