Assistant manager Colin Pascoe and coach Mike Marsh deputised for the sick Brendan Rodgers as Liverpool brushed QPR aside 3-0.
Rodgers was taken ill in London, with back-up goalkeeper Brad Jones and head of performance Glen Driscoll also sent home with the bug.
But the side flourished in their absence, two predatory strikes and Daniel Agger settling the issue in 13 devastating first-half minutes. "This morning he phoned me at eight o'clock," said Pascoe. "I wasn't feeling very well myself this morning, but he's worse than me.
"The way the medical team and the doctors tried to isolate the players and the
staff, they've been fantastic.
"Hopefully they'll have nipped it in the bud and not too many will be affected
"All of the lads were magnificent. The chances we created were phenomenal. We could have had a couple more. Some of our play was exciting to watch and I'm sure our fans will be happy tonight.
"It was fantastic to watch, the way the lads passed the ball around and the weight of our chances."
The only other cloud on the Anfield horizon was a hamstring injury for Joe Enrique, with Pascoe adding: "It looks as if he's got a little tear.
"He was terrific today and he's been a joy to watch in the last few months, so hopefully he's not out for too long."
