Fly half Andy Goode helped mastermind a blistering opening 40-minutes from Worcester as they took complete control of the top-of-the-table encounter.
"Marcel has hit some form early in the season and is playing outstandingly well in attack and defence.
"You can see that not only does he score tries, which is important, but he is also prepared to do the dirty work in defence. He made some crucial tackles.
"He is playing exceptionally well and has been from the start. He looks like he is enjoying his rugby and he is a difficult man to stop, he is all over the place looking for the ball and on that form he is a deadly finisher.
"I'm beginning to understand Goodey now," smiled Hill. "When we have got the win and bonus point his mind is almost on the next important game, which I can understand.
"For the first half he was simply terrific, he ran the game well and when he kicks and clears his lines he has got a massive boot.
"He gets you out of trouble and you are not just clearing your lines and having a lineout on your 22, he is putting them back over the halfway line and that is so critical. Joe Carlisle also kicked well and got good distance, our clearing patterns were also good.
"Goodey was tackling as well, as we have been on at him about that," concluded Hill. "Myles Dorrian, at ten for Bedford, likes to show and go to put the big forwards like Jackson Wray into that channel, but Goodey was up to that challenge.
"You can see that Goodey and others are just warming to the challenge of the play offs and people are getting a bit more excited as we approach March 12."
