After successive home defeats, Manchester City have to wait until Monday before they have a chance to hit the winning trail again when they visit Wigan.
It means both Manchester United and Tottenham will move level on points with the Blues if they win their weekend fixtures against Bolton and Wolves respectively.
And Barry predicts that would give rise to the old stagers trying to turn up the heat on stuttering City, who have secured just one win in their last five games.
"I am sure there will be a few comments made, especially as they are playing before us," Barry said. "That's an ideal time for it. But it has to be all about us now.
"We can't really worry about other teams. We should be focusing entirely on ourselves and winning a game of football."
However, with the ability of the players not in doubt, it is those peripheral factors that City still require.
For instance, the type of siege mentality Ferguson is so good at harnassing at United, which now appears to be taking hold at City judging by the reaction to Glen Johnson's tackle on Joleon Lescott during Wednesday's defeat to Liverpool.
"Any great club needs that sort of mentality to go on and achieve things," Barry added.
"When you look at other clubs like United, that have dominated for a while, you need that to be put into the squad."
Barry can understand why City fans were so annoyed at the decision of referee Lee Mason to not even award a free-kick against Johnson, which the Football Association have since endorsed by not taking any further action themselves.
"Yes, of course," said Barry when asked if there was a sense of injustice at recent events.
"Once the decision has been made and we know Vinny's going to get four games, our fans are going to want to see action every time there is a similar sort of tackle.
"Against Liverpool there were a couple but nothing was done about it."
