David Silva believes Manchester City have the resilience to overcome the absence of captain Vincent Kompany.
City's title challenge has been hampered by the lack of appearances from the influential Kompany, who is sidelined with a calf injury.
Kompany has featured in just nine of City's 20 Barclays Premier League games but they have only conceded once while he has been on the field. In contrast, they have kept only one clean sheet in the 11 games he has missed.
City are still unsure when the 29-year-old will return and Silva knows others will need to step up.
The Spaniard, who turned 30 last week, said: "Vinny is a key player for us and our captain. With or without him in the side we have to work hard to concede less, but it's not just the defence that defends, it's the whole team. It's the same when we're attacking - you need to have everyone helping out going forwards. So it's down to us all to perform our defensive duties and it's something we'll be trying to do to help the cause.
"Any team will miss their captain when they're out and we're no exception but when you look all over the field there are lots of figures willing to step up to the plate when needed.
"We need to get a balance between conceding less but without lowering the total amount of goals we score or chances we create."
City, who are third in the table but just three points behind leaders Arsenal, host Everton tonight in what could prove a pivotal night in the title race. Arsenal face a difficult trip to Liverpool while second-placed Leicester travel to fourth-placed Tottenham.
Silva said: "It's been a very exciting season and, above all, it's very tight at the top."
