The seven-time F1 champion was proven correct as Sunday's race was again won on strategy, while there was little to enthuse other than the odd incident such as Valtteri Bottas' pit stop and Sebastian Vettel's duel with Pierre Gasly.
F1 director motorsports Ross Brawn recognises changes would be ideal but is also acutely aware of their difficulty given the confines of Monte Carlo.
"It is a brilliant event with a massive history, massive atmosphere and it is a race that everyone wants to win, but we all know the limitations of the track," said Brawn to the Daily Mail.
"People often say why don't you change the tyre strategy, or things like that, but the teams adapt.
"We saw it in Singapore a few years ago when the tyres were very soft, the guys just drove very slowly so the pack was close and nobody could pit. The teams find tactics to overcome it."
Brawn insists F1 will not revert to "that sort of trickery", adding: "Where in some racing series you have to divert and go through an overtaking area. I don't think we should do any of that but we will certainly look at the track.
"It will not be the first time that someone has tried to make changes and nobody has got anywhere so far.
"But we do have tools now, our simulation tool for example, and our people will certainly see if there is something we can do."
What do you think?
Move turn 10, after the tunnel, 200m further down Avenue J F Kennedy then have turn 10. This adds 200m of straight to the high speed exit of the tunnel, surely enough to allow overtaking. The road already exists and has been used the opposite way in Formula E, where they drive up Avenue J F Kennedy before turning 180° to come back through the swimming pool section.
