Nathan Brown admitted it was a case of job done after seeing his St Helens side return to top spot in the First Utility Super League after dispatching the London Broncos 58-16 at The Hive.
The Saints raced into a 32-6 lead inside 50 minutes, then withstood a fightback from the hosts, before running in five tries in the game's final 15 minutes to romp home.
Brown said: "I thought for about 30 minutes we were on form and when we scored just after half-time I thought it would be a blow-out.
"But credit to London - I thought their effort was outstanding and they hung in there.
"In fact, considering the position they are in, I thought their attitude was excellent.
"I'm still pretty happy with the result overall.
"I wanted an improvement from last week and I think I got that, and some of our tries showed what we can do as a side."
Mark Percival, Kyle Amor and Jordan Turner eased over inside the first 20 minutes as the visitors started the game on the front foot, before James Woodburn-Hall struck back for the home side.
Turner then grabbed his second, with Paul Wellens adding a fifth score before the break.
Percival added a second of his own, only for Will Lovell and Denny Solomona to cross to reduce the deficit to 32-16.
But Saints upped the ante in the final quarter, with Matt Dawson (two), Luke Thompson, Sia Soliola and Anthony Laffranchi romping home as the visitors cruised past the 50-point mark.
London coach Joey Grima said: "There was a clear difference in effort today from last week.
"Yes, we were still beaten heavily, but I could not question the work the players put in.
"We gave it a go and I think it was a case of us running out of gas as much as anything else.
"I thought St Helens' game management was magnificent and they kept us on the back foot a lot of the time.
"But I asked for enthusiasm from the players and I got a lot of it."
