City face the Bees on Saturday in the early 12:30 kick-off at the Etihad Stadium.
The World Cup starts in Qatar on 20 November – in just nine days – and continues on until 18 December, with the final taking place at Lusail Iconic Stadium.
Guardiola knows there’s a long time to stew if City don’t pick up a positive result against the Bees this weekend.
He wants three points ahead of the break but knows this assignment will be a tough one.
On Brentford, he said: "Same manager, same style.
"They change a little bit the shape this season.
"I remember how tough it was meeting here and away. It will quite similar.
"It’s an early kick off, which is always a little bit more complicated.
"It’s the last game before the stop - we have to do our game and do our job.
"I don't think about a disappointing result, I am always positive before a game.
"One thing is to know exactly what will happen. I cannot answer you [on that]. But always I am positive. But, if it’s not positive, we will come back and try to be better.
"Brentford thinks the same – to finish in the best way possible before the World Cup break. It is no different for them."
We are currently second in the Barclays Premier League table, two points behind Arsenal on the summit who compete in the late game on Saturday with a 19:45 start at Wolverhampton Wanderers.
