Hamilton finished fifth in his McLaren behind a dominant Red Bull one-two spearheaded by Mark Webber who scored his second successive lights-to-flag win in the space of eight days following his previous triumph in Spain.
The suggestion after practice was that Red Bull had not shown their hand as they were far from quickest.
But then come qualifying Webber blew away the field, and again in the race as he faultlessly mastered the unforgiving streets of Monte Carlo.
Webber’s effortless performance means he now leads the championship for the first time in his career, albeit by virtue of the fact he has won two races to team-mate Sebastian Vettel’s one as they are tied on 78 points, whilst the team head the constructors’ standings.
As far as Hamilton is concerned, Red Bull are making it look like child’s play at the moment as he told Press Association Sport: “They have been so quick.
“They didn’t even push in Monaco. In a race you have got to be racing, but they weren’t even pushing. It’s not that it was scary, but it was just taking the Mickey a little bit.”
The only saving grace for 2008 world champion Hamilton is that Red Bull have not dominated in all six races this season, even though they have started from pole at every grand prix.
“If they had also won every race they would be miles ahead by now,” added Hamilton.
“They would have so many points, so for us it’s quite good at the moment to see we’ve got a chance.
“I know at some stage we will catch them up and then we will be racing with them and they would not be having such easy races.
“Hopefully things will turn around, the guys might find something in the wind tunnel and we will have it at the next race.
“I am praying every day that we do, and although I doubt it will be the case, you never know what will happen in this sport.”
Like Hamilton, team-mate Jenson Button fears Red Bull will start to prove uncatchable unless somebody applies the brakes to the momentum they are building.
Button yesterday relinquished his lead in the title race after a cooling cover was left over a sidepod over the radiator, forcing him to retire on lap three with an overheating engine.
Speaking to Press Association Sport, the reigning world champion said: “At the moment you would say the Red Bull is the most competitive car.
“When you are in our position trying to catch them, you can’t have issues.
“You have to be always there fighting, and that is why I was leading the championship going into the race because we were consistently scoring points, whereas now we’re not.
“It’s a little bit frustrating, but it happens and we’ll go to Turkey (on May 30) and hope Red Bull don’t have the advantage they had in Barcelona. I don’t think they will.
“We have to try our best to take points off them because if they are reliable, consistent and don’t make mistakes then over the next few races they are going to be very difficult to beat.”
