Should they lose their FA Cup fourth-round tie at Cardiff on Sunday, City will have a clear 12 days next month to prepare for that testing run of games. "We're not a long ball team, we're maybe more direct than the teams Pep Guardiola plays against".
Warnock feels his side can cause an upset if they play the game of their lives, but admits the size of the task is daunting.
Cardiff's Rhys Healey once had a trial with Sunday's opponents and Warnock could give a chance to the young forward as fellow front-man Danny Ward is out with a knee problem.
Argentina global Sergio Aguero, who has scored 16 goals from 19 Premier League appearances, is set to lead the line once again as Brazilian Gabriel Jesus continues his recovery from injury.
"But I prefer to be in the four competitions and we'll see where we get to. Sometimes you have one more day, sometimes less days because the TV decide".
However, now that the Premiership leaders are heading over the Severn Bridge, Warnock is excited for Cardiff's supporters with the Bluebirds set to welcome their biggest crowd in 41-years.
"I look back to 1991 when we were in Division Two, we played them at Meadow Lane", Warnock said.More news: Swiss mummy identified as ancestor of Boris Johnson

"I am pleased, I could have picked a better draw than Manchester City if I wanted to win the FA Cup but in terms of the tie, I think this is the best one going at the moment, they are great to watch".
"We will have a go but it has been the easiest week of training, because we haven't had a ball, we have just been chasing shadows to get used it", he joked.
Morrison is also looking for his team-mates to have a go at Manchester City and says Cardiff won't be drawn into playing an all out defensive game.
"With Pep Guardiola you can see what he's done with the teams he's managed and competitions he's won".
"If we sit in and let Man City come onto us, it's going to be near impossible". We have played a lot, and we have a lot to play.
Pep Guardiola knows his Manchester City side will be judged on trophies rather than the fantastic performances they have produced this season, as they closed in on the first silverware of a possible quadruple. "They've done brilliantly against Manchester City over the two legs and there's something we can take from that".
